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.

Otherwise, find a plastics manufacturing company to help you get the job done.

Some companies only produce custom plastic parts. Others participate in the packaging and shipping process throughout the process.

In the end, choose the company that best suits your needs.

Jilian Plastic is the reliable mold manufacturer you can trust. We can customize 5-Gallon Pet Preform for you. Welcome to contact us!

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.
