Home > Services > Rapid Tooling > Plastic Injection Molding

Injection molding is one of the most commonly-used plastic part manufacturing processes. It is suitable for production of parts from both thermoplastic and thermoset polymers.

We use natural techniques to manufacture custom high quality plastic molded parts,these parts are widely used in the automotive, medical, cosmetics and consumer industries etc.

At Wintech Rapid, our rapid tooling and injection molding services involve CAD/CAM part and mold design, design for manufacturability (DFM) and Moldflow simulation. We offer overmolding, insert molding and unscrew molding options, as well as weekly tooling schedule reporting and mold trail reporting.

What is DFM?
DFM is short for “Design For Manufacturability”. We extensively study the 3D CAD files you provide and we make sure your design can be built as you intended. We will provide you a report for each part that summarizes the part information (size, weight, material, finish, color, etc.) and addresses any concerns regarding tooling or part design. Not only that, but our DFM also includes our recommendations on how to best resolve any issues to help you revise the design if necessary. All our DFM reports are created at no cost to you.

No regrind material is allowed in Wintech Rapid.
Wintech rapid always use the brand material for the injection.
Dupot, Bayer, BASF, Sabic as well as lots of material agents are our long-term partners that we have can  provide a material COC (Certificate of Conformity) as well as a RoHS report to show proof and guarantee that real resin is used.
We can mold anything from inexpensive commodity resins like PP, HDPE, and styrene to engineering resins like PC, POM, nylon, and TPE all the way to ultra-performance materials like PEEK, polyimide, polysulfone, PPS, and more. And if your needs include fiberglass-reinforced resins, we can accommodate those as well.

Color and finishing
The ranges of finishes we can provide are almost limitless. We routinely polish our tools so that clear parts are truly transparent and we can take that one more step if optical-quality clear parts are required. We can also chemically etch our tools to replicate a wide variety of textured finishes, including selectively textured parts where some areas are textured while other areas remain gloss or matte. As far as colors go, if you provide a color chip, we can match it in most resins. We can also utilize overmolding to achieve both functional and cosmetic improvements.

Our Tolerance

The general tolerance we apply in injection parts is DIN 16901. If you need a tighter tolerance,
we always recommend that you present this information clearly at the quoting stage and also
identify the critical and assembly dimensions first. Injection material, tooling structure, and the
part’s geometry are impacted on tolerance.
