Mold Making

Injection Mold Manufacturer and Plastic Mold Making in China

UTTMould builds plastic injection molds in China for prototype tooling, rapid tooling, production tooling and export mold projects. We support plastic part programs for automotive, electronics, medical device, consumer product and industrial applications.

Our mold making process covers DFM review, mold design, CNC machining, EDM, assembly, mold trial, inspection and modification. This helps buyers reduce tooling risk before moving into injection molding production.

Mold Making Process

1. Requirement review: We check product drawings, 3D CAD, plastic material, expected volume and quality requirements.
2. DFM analysis: We review draft angle, wall thickness, ribs, bosses, gate position, parting line and ejection risks.
3. Mold design: The mold structure is designed for part quality, production stability and maintenance.
4. Tooling and assembly: Mold components are machined, finished, assembled and checked.
5. Mold trial and validation: Trial parts are molded, inspected and adjusted before approval.

Prototype Tooling vs Production Tooling

Factor	Prototype Tooling	Production Tooling
Best use	Samples, functional testing and small-batch production	Stable design and long-term mass production
Initial cost	Usually lower	Usually higher
Lead time	Usually faster	Longer due to higher tooling requirements
Design flexibility	Easier to modify	More expensive to change after approval
Tool life	Shorter to medium	Designed for higher production volume

Plastic Mold Making FAQ

What files are needed for a plastic mold quote?

A 3D CAD file is the most important file. A 2D drawing, material requirement, annual volume, surface finish and tolerance details help make the quote more accurate.

Can UTTMould build export injection molds?

Yes. UTTMould supports export mold projects and can also support production molding if buyers prefer molded parts instead of exported tooling.

What is the difference between rapid tooling and production tooling?

Rapid tooling is usually used for faster validation and lower-volume production, while production tooling is built for stable long-term mass production.

Does UTTMould support mold trial and modification?

Yes. Mold trials and modifications are part of the tooling validation process before final production approval.
