What Are Custom Plastic Parts ?
Custom plastic parts are a kind unique plastic parts, since special demand and functionalities in different applications. Client provide their design concept or drawing files to manufacturers to produce the custom plastic parts that conform with special functions and applictions. Rely on their skilled technique, abondant experiences and advanced equipment, manufacturers take their ideas to produce specific specification plastic parts, deliver these products to client successfully in time. The specific specification plastic parts are called as custom plastic parts.
Types of Plastic Parts
Plastic parts are most common goods, they have different form process. The below is the examples in common.
Injection Molded Part
Created by injecting molten plastic into a mold. Common for high-volume production of precise, complex shapes (e.g., car parts, toys). It has a high productive rate and fast delivery time.
Extruded Part
Made by forcing plastic through a shaped die; often used for pipes, tubes, and profiles. It is a big size streamline production and consistence.
Blow Molded Part
Produced by inflating molten plastic into a mold, commonly used for hollow objects like bottles and containers.
3D Printed Part
Fabricated by adding layers of plastic material, used for prototypes or custom parts. Some present model and first trial sample testing is commonly used.
Common Plastics Material Used
- Polyethylene (PE): Durable, strong corrosion resistance, used for plastic packaging and containers.
- Polypropylene (PP): Hardness and high stess, Used in automotive parts, packaging, and textiles.
- Acrylonitrile Butadiene Styrene (ABS): Common electronic consumer goods, gifts and daily goods.
- Polyvinyl Chloride (PVC): Good toughness,Used for pipes, window frames, and medical devices.
From small precision components in electronics to large structural parts in vehicles or machinery, plastic parts play a vital role in various industries. If these parts are custom plastic parts, we should produce them according to client’s special requirements and desire. Because we have ability to finish any custom plastic parts from any client.
Car Key Case Mat—Custom Plastic Part Project
Zinc casting box, houses the car key and can protect the car key from crashing by weights by accident. In order to prevent splashing and flooding from water, diversity shapes plastic mats are used for protecting electric components and chips. So this plastic water proof mat is indispensable part for a metal car key cover box.




This kind of specific plastic water proof mat is made of soft plastic material, which is typical plastic resin. It can be made by precision plastic injection mold for the car key different shape. Sometimes some mat is also on which surface engraved with operation patterns due to these mats is not transparent.
In summary, these plastic parts create different applications. Faces the growth of personalized and tailored requirements in automotive industry, custom plastic parts are more challengable, especially car key cover parts,which is need of more innovation and investment.
Plastic Car Key Case Cover Is Attractive, Too
Plastic car key cover may be made of ABS material, and it is not transparent, so on the surface of which engraved or printed with some operation labels. It conform with International Environmental Protection Standard, Belong to green ECO friendly products, but also custom appearance design and production is acceptable. These custom plastic parts are attractive and provide our added valued services.
