Injection Mold Manufacturer in China

Plastic Mold Making for Prototype and Production Projects

UTTMould is a plastic injection mold manufacturer in Huizhou, Guangdong, China. We support overseas buyers with DFM review, mold design, machining, assembly, mold trials, inspection and tooling modification for prototype, production and export mold projects.

Each tool is planned around the part function, resin, expected volume, tolerance, surface requirement, tool life and delivery schedule. This helps reduce late changes and gives buyers a clearer path from sample approval to molded-part production.

Send CAD files, drawings and project volume to request a tooling quote.

Export Molds and In-House Molding

For an export mold project, the deliverable is a tool for the buyer's production equipment. Confirm the destination machine interface, mold specification, trial sample review and handover documents during RFQ review. For a tool retained at UTTMould, agree the molded-part requirements, sample approval and production quantity before release.

Review injection molding services in China or send CAD files and your tooling requirements for RFQ review.

Mold Manufacturing Process

Requirement review: We check product drawings, 3D CAD, material, annual volume, finish and quality requirements.
DFM analysis: We review draft angle, wall thickness, ribs, bosses, gate position, parting line and ejection risks.
Mold design: The structure is designed for part quality, process stability, maintenance access and production needs.
Machining and assembly: Components are machined, finished, fitted, assembled and checked by the tooling team.
Trial and validation: Trial parts are produced, measured, reviewed 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

For a mold-making project, define whether the deliverable is an export mold, a tool for sample validation or tooling for ongoing part production. Compare rapid and production tooling requirements when selecting the tool specification. If the main deliverable is molded parts, review the injection molding project requirements.

Project Example: Top and Bottom Housing Mold

This export tooling project used a specified 4+4-cavity arrangement for paired housings. UTTMould handled mold design and manufacturing, followed by trials and small-batch trial production. The mold was accepted and delivered.

Mold Making Buyer FAQ

What mold life can UTTMould support?

Mold life depends on steel choice, part material, product structure, cavity count and maintenance plan. UTTMould can recommend prototype, rapid or production tooling based on expected volume.

What files are needed for a mold making quotation?

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

Can UTTMould build export molds as well as molds for in-house molding?

Yes. UTTMould can build export molds for customer production lines or build molds that stay with UTTMould for molded-part production and delivery.

Do you provide DFM feedback before mold manufacturing?

Yes. We review wall thickness, draft, ribs, bosses, gate location, parting line, ejection, undercuts and other moldability risks before tooling begins.

Does UTTMould support mold trial and modification?

Yes. Trial runs, part measurement, tooling adjustment and modification are part of the validation process before final production approval.
