As an experienced SMC mould maker, we design and manufacture SMC moulds to the highest quality level. Our mould designers convert simple sketches or 2D drawings into 3D models of the molds to ensure accurate molding.

The design specifications of SMC moulds also contribute to the production of FRP products. The elimination of sharp corners around the edge of the part avoids unnecessary stress on the molded part and reduces fiber wear. Molds should be designed to ensure consistent wall thickness at all times. Large variations in wall thickness can lead to inconsistent filling.

Where thicker or thinner walls are required, avoid sudden changes in wall thickness, as this may create areas of high shear, which can damage the fibers and become stress concentrations. When filling, use a thicker wall and flow into the thin-walled part and finally fill the thin-walled part. For SMC molds, keeping the wall thickness below 4mm promotes uniform flow and reduces the possibility of sinkage and voids. It is also essential to consider how the material will be made into the SMC mold, as many fiber degradations can occur in these areas if the runners and gates are not appropriately designed to guide the material into the cavity. The minimum thickness of the gate should be 2 mm.

As a quality-conscious company, we perform dimensional checks on molds to ensure accuracy, and all molds are subjected to any other type of testing required. We provide full technical support, make repairs and changes as needed, and document all maintenance activities as part of our history.

With our production flexibility and dedicated customer service, we can produce most SMC molds on time and provide emergency service for time-critical projects. We listen carefully to our customers and offer solutions that will improve the quality of their products.
