Plastic parts can be co-injected
Co-injection is a polymer injection process in which different types of polymers are injected into the same mold and the core material is completely encapsulated. The benefits of this process include:
Reduce costs by using cheaper filler materials as the invisible core of the product.
Combine the desired properties or mechanical properties of the selected polymer, such as color, density, elasticity, and the like.
Since the melting point of the secondary plastic is lowered, the use of energy is reduced.
Plastic parts can be quickly formed
The plastic injection molding process reliably produces a large number of high quality, consistent units from a Pet Preform Mould. Although setting up the machine can be time consuming, once the injection mold is designed to meet specifications and the press is programmed, the molding process itself is very fast compared to other forming methods.
The plastic injection molding process involves a high degree of automation, which greatly saves production costs. Many steps can be performed by an operator controlled machine or robot, which helps increase throughput. A common question is, “How fast is the part manufacturing?” It depends mainly on how many impressions there are in the tool, but usually the cycle time can be between 15 and 30 seconds.
In the past many years, the design and manufacture of China Pet Bottle has made tremendous technological advances, and they are used in such a wide range of applications because they are uniquely capable of providing different performances and providing advantages unmatched by other materials.
