Jiangzhi offers custom plastic injection molding for both low-volume and end-use production. Typically, we use steel as the tooling material to ensure mold durability. Our mold costs start at only $500. Additionally, we provide a variety of plastic resins, allowing you to choose the perfect material for your project.


What is Plastic Injection Molding?

Plastic injection molding is a manufacturing process where molten plastic is injected into a mold cavity to form a specific shape, which is then cooled and solidified into a final part. It is a popular technique for producing high volumes of complex plastic parts, ranging from small intricate components to large automotive parts.

Furthermore, proper mold design and careful control of molding conditions are crucial for producing high-quality parts. Explore our mold & tooling service and quality management.

FAQs of Plastic Injection Molding

What is the hardest plastic for injection molding?

Polycarbonate is one of the most shatter-resistant plastic materials available for use in injection molding.

Plastic materials for injection molding range from commonly used polymers to specialty plastics and polymer blends. There are hundreds of different plastic resins available, and they each have different end-use properties and processing requirements.

In the most of the time, the plastic they are formed can be recycled.

The lead-time for a plastic injection mold can be quite variable and depends on several factors. In general, you can expect the lead-time to range between 4-12 weeks, but even this timeframe could vary depending on complexity and scale of production.
