Can a plastic mold maker also do production parts using the molds?

Yes. A plastic mold maker in China like Richfields can not only create molds but also handle the production of parts using those molds. This integrated approach ensures consistent quality, faster turnaround, and seamless transition from prototyping to full-scale manufacturing.

Do plastic mold makers only make new molds, or can they modify existing ones?

Plastic mold makers in China can both create new molds and modify existing ones to meet updated specifications or improve part performance. This flexibility allows businesses to optimize production without starting from scratch, saving time and cost.

What You Need to Know About Mold Making

A mold is a core tool in plastic injection molding, shaping molten plastic into a final part. During injection, molten material is injected into the mold cavity where it cools and solidifies into the intended geometry. Without a properly designed mold, accurate plastic components cannot be reliably produced at a consistent scale.

The primary role of a plastic mold maker in China is to design and manufacture precision tools for production. Mold design revolves around selecting the appropriate cavity structure, steel grade, and thermal properties to match the intended polymer.

The common materials used in plastic mold making include the following, each chosen based on production volume and material compatibility:

Aluminum
Copper
Silicone Rubber
Epoxy Resin
Nickel-Based Alloys
Steel

Product Design & Requirement Review

Plastic mold makers in China begin by analyzing product specifications such as dimensions and material requirements. This ensures the mold design aligns with the intended application and production goals.

Design for Manufacturability (DFM) & Engineering Analysis

Engineers evaluate the design for potential production issues, such as shrinkage and abnormal flow behavior, to optimize the part for efficient, stable manufacturing.

Mold Design Development

A detailed mold structure is created with proper gating systems and cooling channels. These help plastic mold makers in China define how the molten plastic will fill and form the final part.

Mold Fabrication & Machining

The mold is manufactured using Computer Numerical Control (CNC) Machining and Electrical Discharge Machining (EDM). Each component is produced with strict dimensional accuracy for reliable performance.

Mold Testing

Trial runs are conducted to validate mold function, material flow, and part accuracy. Any defects or inconsistencies are identified during this stage.

Final Adjustments and Approval

The mold is refined based on test results to improve performance and eliminate defects. Once approved, it is cleared for production use.

Mass Production and Quality Control

The output from plastic mold makers in China is used for full-scale injection molding under controlled conditions. Continuous quality checks ensure consistent output across production batches.

Family Mold

Richfields produces family molds designed to accommodate multiple cavities within a single tool. This setup allows multiple parts to be produced in a single cycle, improving production efficiency and reducing overall manufacturing costs. Family mold manufacturing is commonly used for multi-part assemblies requiring synchronized production.

Hot Runner Molds

Our hot runner molds are designed to maintain controlled temperatures throughout the injection process. These molds are suitable for high-volume manufacturing that requires consistent part quality.

Cold Runner Molds

Plastic mold makers in China use cold runner molds for applications that require simpler tooling systems and material flexibility. The design allows molten plastic to solidify in the runner system before ejection, making it suitable for cost-efficient production runs.

Unscrewing Molds

Unscrewing molds are used for producing threaded components such as caps, fittings, and connectors. These molds are engineered with mechanical or hydraulic systems that allow precise unscrewing during part ejection.
