Why Choose Us

Rich Experience

Ningbo Yowin Pipe Industry Co., Ltd. has specialized in the production of various plastic injection moulds, including precision pipe fitting moulds, custom bathroom plastic part moulds, and household appliance plastic component moulds, for more than 15 years.

Global Shipping

Our production South America market (Argentina, Brazil, Bolivia, south Africa, America, Mexico, UK, Philippines and Thailand market Etc).

Production Capacity

Our plastic injection moulds feature a strong production capacity to meet both bulk orders and personalized needs. Currently, we operate 5 advanced mould processing workshops with professional equipment, capable of manufacturing up to 300 sets of plastic injection moulds per month—amounting to 3,600 sets annually under normal production circumstances.

Quality Control

Made from high-strength, wear-resistant alloy materials, our plastic injection moulds are engineered to ensure stable performance during long-term production runs and maintain high precision in product forming. The precision-machined cavities and cores guarantee consistent dimensional accuracy of the injected parts, while strict tolerance control (within ±0.02mm) ensures that each mould meets the rigorous standards required for mass production of plastic components.

Applications of Plastic Injection Moulds

Pipe Fitting Industry: Critical for manufacturing precision plastic pipe fittings such as elbows, tees, and couplings, ensuring consistent dimensions and tight seals for plumbing systems in residential, commercial, and industrial settings.

Bathroom and Household Appliances: Essential for producing custom plastic components like shower handles, faucet bases, and appliance casings, enabling mass production of uniform, durable parts that meet ergonomic and aesthetic requirements.

Industrial and Automotive Sectors: Valuable for creating specialized plastic parts such as machinery enclosures, automotive interior components, and fluid transfer connectors, supporting efficient production of high-performance, cost-effective industrial products.

FAQ

Q: What is a plastic injection mould?

A: A plastic injection mould is a precision tool used in manufacturing to shape plastic products through the injection moulding process. It consists of two main parts (the cavity and core) that form the desired shape when molten plastic is injected into the mould, cooled, and solidified.

Q: What materials are plastic injection moulds made of?

A: Common materials include high-grade tool steels (such as P20, H13, and S136) for durability and heat resistance, as well as aluminum alloys for lower-volume production or prototyping due to their faster cooling properties and cost-effectiveness.

Q: How long does a plastic injection mould last?

A: The lifespan depends on factors like material, maintenance, and production volume. Tool steel moulds can last for 100,000 to over 1,000,000 cycles, while aluminum moulds typically endure 10,000 to 100,000 cycles, making them suitable for short to medium production runs.

Q: What factors affect the cost of a plastic injection mould?

A: Key factors include the mould’s complexity (shape, size, and number of cavities), material (tool steel vs. aluminum), precision requirements, and additional features like hot runners or cooling systems. More complex moulds with higher precision demands generally cost more.

Q: How is the quality of a plastic injection mould ensured?

A: Quality control involves rigorous testing of mould dimensions, surface finish, and cavity/core alignment using precision measuring tools (such as CMMs). Additionally, trial runs are conducted to check for defects in the injected parts, ensuring the mould produces consistent, high-quality products.

Q: Do you test all your plastic injection moulds before delivery?

A: Yes, we perform 100% testing on all plastic injection moulds before delivery, including dimensional inspections, trial injections, and functionality checks to ensure they meet design specifications and production requirements.

Q: Can plastic injection moulds be customized for specific products?

A: Yes, plastic injection moulds are highly customizable. They can be designed to match the exact dimensions, shapes, and surface finishes of the target product, whether it’s a pipe fitting, bathroom component, or household appliance part.

Q: Do you test all your goods before delivery?

A: Yes, we have 100% test before delivery.
