Method For Preventing Pet Preform Defects

Posted by nicolepreform on Jan 17, 2019 in News

Defect. defect. Structural integrity is reduced.

No matter what you say, these words are not what manufacturers are willing to hear.

However, whether you are new or experienced in the injection molding process, they can happen.

The best way is to familiarize yourself with common defects and understand why they happen. Here are some of the most common defects in Pet Preform and what you can do to prevent them.
Deformation streamline

Strange discoloration, wavy bands, or other imperfect stripes are called streamlines. This type of defect is usually caused by too much temperature change as the part cools and becomes solid.

Solution: Adjust flow rate and cooling time to produce a uniform product. This can be done in a number of ways, depending on the design specifications and materials used. You can increase the injection pressure and temperature to keep the material hotter. You can also make design adjustments such as rounded corners or smaller or wider features to promote more even flow.
Burn marks

Black focal spots along the edges and surfaces of the part are called burn marks. These burn marks are usually caused by overheating and overheating of trapped air taken in during the injection process.

Solution: Eliminating the air trapped in the mold is the key to preventing burn marks. You can reduce the jet speed, allow air to escape through the vents, or shorten the cycle time so that the air does not overheat. The less trapped air or the lower the temperature, the less likely the burn marks will be.

Customized Production Of Pet Bottle Preform

Posted by nicolepreform on Jan 15, 2019 in News

Plastics, also known as polymers, come in a wide variety. They are composed of different elements such as hydrogen, chlorine, oxygen and nitrogen. They also have high molecular weight.

Manufacturing plastics are often designed to mimic the ingredients of natural materials such as wood.

They are made by the conversion of natural products. Sometimes they are made up of natural chemicals, petroleum or basic chemicals in coal.
Manufacturing custom Pet Bottle Preform parts

Producing custom plastic parts usually follows a series of events. The only difference is that the main manufacturing stage is based on the geometry of the plastic part.

Their actual requirements are also considered.

One idea of ​​how to make plastic parts from plastic injection molding is crucial.

Once you have learned the basics of production, these steps become relatively easy.

Here’s a general idea of ​​how to make custom plastic parts.
Propose a design

It is important that you design a design for the custom plastic part you want to create.

First draw a design sketch on a piece of paper.

In the end, your sketch should have enough detail so you can draw its 3D model.

If you don’t have this skill, please ask a professional to help.

This is also a phase in which the main changes happen to make the product achievable.

Presenting a design to a team of experts will greatly help you achieve your goals. If possible, ask a manufacturing technical expert to help complete your design.
Decide which plastic molding process is best for the design

There are different molding methods for making plastics. Custom injection molding is arguably the most popular technology.

Plastic injection molding is used to produce plastic parts using a simple mold opening and closing function.

The process you choose will depend on the different variables. These include your initial design, the number of parts required, and the overall use of the product.
Build prototype

This will increase your total expenses, but developing a prototype like a final product will be a huge help.

In the long run, prototypes can also avoid wasting time and resources.

There are tons of prototype tools that can be used to make custom plastic parts, such as resin prototype machines.

Building a prototype will allow you to fix problems that may not be apparent in the 3D model of your design.

It also determines the efficiency and functionality of the final product.

If you have the methods and tools to make your custom plastic parts, make them the way you choose.

Pet Preform Need To Withstand High Temperatures

Posted by nicolepreform on Jan 12, 2019 in News

Usually, the PET resin starts to soften at 70 ° C or higher. This softening temperature is called TG (grass transition temperature) of PET. It is assumed that when the Pet Preform leaves in the atmosphere above 70 ° C, the bottle neck will begin to soften, and almost the size will shrink, and the bottle mouth will also be deformed.

In particular, the demand for beverages such as juice, oolong tea, coffee drinks and lactic acid beverages is expanding in recent years. However, almost all beverages are filled into PET bottles at temperatures above 85 ° C. After that, the PET bottles are placed on the filling line, then the bottles are inverted and the contents of the bottle are filled with high temperature contents. Disinfect for a period of time.

Therefore, the mouth of a PET bottle must be able to withstand high temperatures. Usually, the state of the neck finish of the PET preform is amorphous because it is injection molded, which is why it is not heat resistant above 70 °C. In other words, the finish has dimensional shrinkage and shape distortion during hot filling and can cause fatal defects in the PET bottle, such as microleakage.

However, PET has a property of becoming heat-resistant upon crystallization. The density of amorphous PET is 1.365 g / cm3, but heat resistance is not considered. When the crystallinity is increased from 1.365 to 1.380 (the crystallinity index is increased from 25% to 39%), the density is higher.

As a professional China Pet Bottle manufacturer, Jilian Mould has gained many customers’ trust and praise in the market with years of experience. We have seen the development trend of this industry and are determined to bring you more products that suit your own wishes.

Successful Production Of China Pet Bottle

Posted by nicolepreform on Jan 10, 2019 in News

Plastics have thousands of different base chemicals, derivatives and additives that are formulated to cover a wide range of functional and aesthetic properties. To simplify the process of finding the material that best fits a Pet Preform, let’s look at two broad categories of plastics: thermoplastics and thermosets.

Thermoplastics are the most common type of plastic. The main feature that makes them different from thermoset plastics is that they can undergo multiple cycles of melting and curing without significant degradation. Thermoplastics are typically provided in the form of small particles or flakes that are heated and formed into the desired shape by various manufacturing processes. This process is completely reversible because no chemical bonding occurs, which makes it possible to recover, melt and reuse thermoplastics.

Common materials:

Acrylic acid (polymethyl methacrylate)
Acrylonitrile butadiene styrene
Polylactic acid
Polypropylene (polypropylene)
Polyvinyl chloride

Thermoset plastic

Compared to thermoplastics, thermosets (also known as thermosets) remain permanently solid after curing. The polymer in the thermoset material crosslinks during curing caused by heat, light or suitable radiation. This curing process forms an irreversible chemical bond. Thermoset plastics decompose when heated, rather than melting, and do not reform upon cooling. It is impossible to recover the thermosetting material or return the material to its basic composition.

Common materials:

Epoxy resin
Vulcanized rubber

Want to choose a cost-effective China Pet Bottle manufacturer? Then Jilian mold is a very good choice, we have many years of experience in this industry, I believe that we can provide you with comprehensive help to ensure smooth production.

Aseptic Processing Of Fruit Juice Production Line

Posted by chirtyjimei on Jan 9, 2019 in News

Aseptic processing is a technique in which a sterile product of a Fruit Juice Production Line is packaged in other sterile containers under sterile conditions to extend the shelf life of the product and does not require refrigeration. The process includes separately sterilizing the product and package, then filling the pre-sterilized product into a pre-sterilized package and sealing (sealing) the pre-sterilized package in a sterile chamber under sterile conditions. Packaging materials are usually sterilized with chemical bactericides such as hydrogen peroxide, and foods are sterilized by heat at relatively high temperatures for much shorter periods of time, thus helping to maintain the nutritional value and sensory quality of the product. ) The pulp/fruit pulp is much better.
Aseptic processing consists of three stages

Product sterilization
Sterilization of packaging materials
Keep sterility during the packaging process.

Bags in boxes and buckets are much lighter and cheaper than tin and glass containers, and aseptic processing and packaging technology is rapidly gaining a dominant position.
Process - feed the pulp into the preheating slide (30 ° C to 65 ° C)
Heating section: – Increase pulp temperature (65 ° C to 95 ° C) for 50 seconds.
Cooling section: After heating, reduce the temperature of the pulp/concentrate by means of tower water 32 ° C (95 ° C to 40 ° C)
Final cooling section: After cooling, the temperature of the pulp (70 ° C to 30 ° C) needs to be reduced with the aid of glycol water.

The method basically involves placing the food contained in the sealed sterile bag at a low temperature for a period of time and rapidly cooling to ambient temperature. Therefore, the microorganisms present in the food are almost killed or completely inactivated, thereby preventing corruption. Fruits and vegetables and their products, as well as all foods with a pH below 4.6, are heat treated in near boiling or boiling water at 95 - 100 ° C, while foods with a pH above 4.6 are sterilized at temperatures of 100 - 121 ° C

In foods with a pH above 4.6, spore growth is not inhibited. Because of the high heat resistance of spores, relatively high temperatures are required to destroy almost all living bacteria, including vegetative cells and spores. Therefore, these foods are heat treated using an RSSP (Rotary Scrape Pasteurizer). In modern times, the process industry has achieved a high degree of mechanization and automation.

Aseptic processing and ultra-high temperature technology are the latest technologies introduced in the field of food heat treatment, most initially in cans.
Advantages of aseptic processing in Milk Processing Plant

Sterile foods - Aseptic processes remove bacteria and harmful bacteria from food.
No refrigeration - once the food is processed, there is no need to refrigerate, which saves energy.
Preserving nutrition – the nutritional quality of the food is not affected by less calories.
Flexibility - It offers the flexibility to use a variety of container sizes and even increases the likelihood of adding bioactive and heat sensitive ingredients after processing.

Pet Preform Manufacturers Focus On R&d Innovation

Posted by nicolepreform on Jan 8, 2019 in News

The use of Pet Preform machines adds to the advantages of product manufacturers as it offsets fluctuations in the demand for beverage and bottled water markets. In addition, the increase in sales of packaged goods and consumer preferences for a small number of packaged products have increased the use of PET in packaging and have had a positive impact on the PET preform market. The high speed of PET preformers and their application in various end industries are other factors supporting the growth of the PET preformer market. However, the high cost associated with PET preforming machines may hinder the growth of the PET preform machine market. Reducing the cost gap between single-step PET blow molding machines and PET preformers may further limit the use of PET preformers.

PET preformer market: company development and industry level trends

As the packaging industry reduces its carbon footprint, PET preform machinery manufacturers are focusing on developing systems suitable for the production of lightweight PET preforms without changing the performance of the bottles.

China Pet Bottle manufacturers have made technological advances in the market. With the development of electric press technology, manufacturers are now able to reduce operating costs by reducing energy consumption.

Milk Powder Making Machine Chooses Shanghai Jimei

Posted by chirtyjimei on Jan 7, 2019 in News

In the past 10 years, the best cleaning methods in many industries have changed. Unlike other manufacturing industries, the food and beverage processing sector is emerging from outdated methods as they focus more on reducing cross-contamination, reducing bacterial accumulation and increasing productivity.

For complex and safety-conscious food factories and Juice Production Line, the use of traditional tools such as rags, scrub brushes and hoses is no longer an ideal choice. The following are the best cleaning methods that should be followed in the food and beverage processing industry.
Wet cleaning and dry cleaning

Traditional cleaning methods include rinsing chemicals, waste, oil and grease. The main drawback of this method is that it does not agitate the surface, which is the basis for deepening the surface, including any pores and cracks. A process that combines a 4-in-1 method of washing, scrubbing, steaming, and drying food processing equipment and surfaces is desirable. These steps not only sterilize (if the steam temperature is high enough), but also mechanical agitation to remove food debris, dirt and dirt.

When viewing the steam cleaning process, it is important to use “dry” steam. Dry ingredients significantly reduce the risk of residue build-up or wet/wet floors, which can cause slips and falls.

Another key factor when it comes to wet and dry cleaning is that some processing equipment should not get wet. Wet equipment can cause mechanical failure and rust.
Automatic and interval cleaning

Traditionally, cleaning can only be done before or after production. If cleaning occurs during production time, the machine needs to be shut down for cleaning.

Online cleaning systems are a modern method that allows food and beverage processing equipment to be steamed, vacuumed and removed in one process without the need to stop and exchange equipment or tools. This greatly reduces the risk of contamination downstream of the production line. During the production process, the surface will be deeply cleaned rather than wiped at the end. It also reduces resources, manpower and downtime.
Verification of the cleaning process

In many food and beverage processing plants, the increase in regular ATP testing is becoming a standard. The ATP test allows the detection of microorganisms and subsequent prevention of contamination.

The use of invisible or fluorescent lights is becoming a popular audit tool in industries where pollution prevention or infection is critical. Some microorganisms can be detected under fluorescent light.

Cleaning audits can go a step further when using fluorescent tools. Areas to be cleaned in the factory can be marked with “invisible marks”. Once the cleaning is complete, you can use the fluorescent torch to see if the invisible mark is still present. If the invisible traces still exist, the surface is not sufficiently cleaned.
More stringent infection control program

The process of implementing a “protection” food and beverage processing environment is almost as important as cleaning itself.

An example of a protective process can be seen in the use of ultraviolet (UV) irradiation methods. UV light continues to protect and disinfect the environment after cleaning. If a surface is contaminated during production time, the microorganisms will grow for 12 hours or longer when the plant is shut down for one day or non-production time. Ultraviolet light can act as a “night watchman” of bacteria during production downtime, thereby reducing the risk of such contamination.

Jimei Creates More Convenience For The Mini Dairy Plant

Posted by chirtyjimei on Jan 4, 2019 in News

UHT milk has been subjected to UHT Milk Machine ultra-high temperature treatment to kill spores in milk (such as botulism), thereby extending the shelf life of milk to 6-9 months. The ultra-high temperature treated milk can be placed on the shelf without being frozen. Once opened, it does need to be refrigerated and consumed within a few weeks. UHT treatment heats the milk to 135 ° C (275 ° F) for 2 seconds, which also reduces some of the nutritional value of milk, and does not require continuous cooling.

Why did you start ultra-high temperature treatment? Mainly for the purpose of better transporting milk, but also for people to hoard milk without the need for a large refrigerator. That’s why UHT milk is so popular in Europe, where people tend to have smaller apartments and thus have smaller refrigerators. UHT milk is packaged in a sterile container that is aesthetically pleasing, rectangular and compact. Ultra-high temperature milk is also popular in warm climates, or in areas where electricity is unstable or damaged by natural disasters such as hurricanes. Proponents of the UHT dairy farm believe that UHT milk has several advantages: its regular shape improves transport efficiency, and in addition, they are flat before the aseptic carton is filled, which means they take up less space. It is another transportation efficiency. All of this efficiency means less greenhouse gas emissions.

Compared to regular pasteurized milk, UHT milk has two main advantages, making UHT very suitable for the import and export of fresh liquid milk. One advantage is the longevity milk properties of UHT milk. As long as the bottle is not open, it can be stored for more than one year. The possibility of storage gives us a second very important advantage of this liquid drinking milk. The second advantage is that the product can store the entire storage period at room temperature while waiting to move on the market shelves.

Therefore, the demand for UHT milk processing equipment in the Mini Dairy Plant is growing. Shanghai Jimei also sees such a market demand and is constantly innovating and researching in this field, aiming to provide more equipment for everyone!
