Injection moulding is one of the most economical and versatile methods of producing rubber and plastic products, offering excellent opportunities for entrepreneurs and small businesses.
Here, we explain what injection molding is and what are the benefits to help you get your company off the ground, improve business operations, or just satisfy a curious mind.

What is injection molding?
Injection molding is the manufacturing process of injecting pvc raw materials into molds to produce items/parts of various shapes, sizes and colors. Most commonly, thermoplastic or thermoset polymers are used to produce each item. The process is cost-effective, reliable and efficient, especially for applications that require a large number of identically precise, close-tolerance molds.

What are the benefits of valve injection molding?
Plastic injection molded parts often prove to be an economical option and are highly sought after due to the excellent repeatability of the injection molding process. In other words, the results are always consistent, which makes it ideal for producing large quantities of the same product at an affordable price.

I want a product to be injection molded. What initial tool cost can I expect?
The cost of the initial tool depends largely on the size and complexity of the associated components. In addition, the complexity of the mold design and the number of mold cavities also affect the cost.

How do I know which polymer is best for my application?
The polymers used depend on the nature of the proposed application. For example, impact-modified polymers are recommended for most automotive components, especially drawbar end caps, grilles, and the like. At the same time, UV-stabilized polymers are more suitable for components for outdoor applications.

What is the turnaround time for injection molding?
Turnaround time depends on the number of cavities per product, the complexity of the machinery and mold cooling systems used, and inventory agreements. The quality of the mold often depends on how much money is invested in the process, which in turn affects cycle time: the better the quality of the product, the longer it usually takes to produce.
