Injection Mold Design & Mold Building

We usually need 3D CAD files, 2D drawings if available, material requirements, part quantity, surface finish requirements, tolerance requirements, expected mold life, production volume, and any assembly or functional requirements. STEP, STP, IGS, X_T, and SolidWorks files are commonly used.

Yes. We build custom injection molds for plastic parts based on customer drawings, 3D files, samples, or product requirements. We can support prototype molds, production molds, export molds, multi-cavity molds, insert molds, overmolding molds, and 2K injection molds.

We can manufacture different types of plastic injection molds, including single-cavity molds, multi-cavity molds, family molds, insert molds, unscrewing molds, hot runner molds, cold runner molds, prototype molds, mass production molds, and export molds.

A prototype mold is mainly used for product verification, sample testing, and low-volume trial production. A production mold is designed for stable mass production, longer mold life, higher efficiency, and repeatable production quality. Production molds usually require stronger mold steel, better cooling, and more durable mold structures.

Export molds can be built according to customer-specified mold standards, export requirements, mold drawings, spare parts needs, testing records, and packaging requirements.

Yes. We can support complex plastic parts with ribs, screw bosses, snap-fits, undercuts, side holes, threads, clips, sliders, lifters, inserts, and assembly structures. Our engineering team reviews the part design and mold feasibility before mold manufacturing.

Yes. Before mold design, we can provide DFM analysis to review wall thickness, draft angles, undercuts, parting line, gate position, ejector layout, material selection, and molding risks. DFM helps reduce tooling problems and improve mass production stability.

Yes. For complex parts, large parts, thin-wall parts, transparent parts, or high-volume production projects, mold flow analysis can help evaluate filling balance, gate location, weld lines, air traps, shrinkage, and warpage risks before mold building.

Mold steel is selected based on plastic material, production volume, surface finish, part structure, mold life requirement, and cost target. Common mold steels can be selected for prototype molds, medium-volume production, high-volume production, transparent parts, or abrasive materials such as glass-filled plastics.

Yes. We can design and build multi-cavity injection molds to help improve production efficiency and reduce unit part cost for suitable high-volume projects. Multi-cavity molds require careful design of the runner system, cooling system, cavity balance, and dimensional consistency.

Yes. We can build insert molds for plastic parts combined with metal inserts, brass nuts, threaded inserts, pins, terminals, magnets, sleeves, or other pre-formed components. Insert mold design should consider accurate insert positioning, stable loading, and bonding around the insert.

You can send us your 3D files, 2D drawings, material requirements, expected production quantity, surface finish, tolerance requirements, and project application. If you only have a sample or idea, we can also support reverse engineering, product design, and DFM review before mold quotation.
