Plastic Injection Mold Making

Plastic Injection Mold Making

Yinuomold provides custom plastic injection mold making services for B2B customers who need plastic part development, mold tooling, and production preparation.

Our mold making service is suitable for custom plastic parts used in consumer electronics, home appliances, industrial equipment, automotive-related parts, and other plastic component projects.

Our Mold Making Scope

Our plastic injection mold making service may include:

– Drawing and 3D file review
– DFM evaluation
– Mold structure planning
– Prototype mold making
– Production mold making
– Mold trial
– Sample inspection
– Mold modification
– Preparation for injection molding production

Mold Types

We can support different mold requirements depending on the project stage and production quantity.

Common mold types may include:

– Prototype molds
– Production molds
– Single-cavity molds
– Multi-cavity molds
– Insert molds
– Overmolding molds

Project Evaluation

Before mold making, we usually review the part structure, plastic material, wall thickness, draft angle, tolerance requirements, surface finish, gate position, ejection method, and estimated production quantity.

This evaluation helps reduce mold risks and improve production stability before mass production.

Common Plastic Materials

The final plastic material should be selected based on product function, appearance, strength, temperature resistance, flexibility, cost, and application environment.

Common materials may include:

– ABS
– PC
– POM
– Nylon
– PP
– PE
– PMMA
– TPU / TPE

Quality Control

For mold making projects, we focus on tooling accuracy, sample verification, mold trial results, and modification confirmation. The process may include drawing review, DFM evaluation, mold structure checking, trial sample inspection, dimension checking, and final mold confirmation.

From Tooling to Production

After mold confirmation, the project can move into injection molding production. This helps customers manage the full process from part development and mold making to sample approval and mass production.
