Compression mould is HC Mould's biggest business, and we specialized in SMC/BMC/GMT/LFT/HP-RTM mold for more than ten years.
SMC is a mixture of polymer resin, insert fillers, fiber reinforcement, catalyst, pigments, stabilizers, release agents, and thickeners. Manufacturing of SMC is a continuous in-line process.
This process produces high strength, complex parts in a wide variety of sizes. Matched metal dies are mounted in a hydraulic molding press. Thematerial charge is manually or robotically placed in the mold; the heated mold halves are closed, and up to 2000 psi of pressure is applied. Cycle time ranges from one to five minutes, depending on part size and thickness. Features such as ribs, bosses and inserts can be molded in.

BMC is available in bulk bags as well as slug form. Themixing operation can be done in a number of ways. There are three methods for combining glass with paste: a continuous screw mixer, a sigma blade mixer and a plough blade mixer. Theprocess chosen is dependent upon specific product properties, product form and volume.
Depending on the end-use application, compounds are formulated to achieve tight dimensional control, flame resistance, high dielectric strength, corrosion and stain resistance and color stability. Its excellent flow characteristics make BMC mold well suited to a wide variety of applications requiring precision in detail and dimensions. Thematerial is available in a wide variety of colors.
Besides, BMC mold is suitable for either compression molding or injection molding. Compressing molding of BMC is used to produce complex components such as electrical equipment, car components, housings for electrical appliances and tools, in large industrial volumes.

Meanwhile, D-LFT (Direct-long fiber thermoplastics) is available for injection or compression molding. Most D-LFT systems, feed glass roving into a twin-screw extruder (TSE), where it is chopped by the screws as it is mixed with molten polymer and additives that have been metered in separately. To improve surface finish, some systems use knives to prechop the roving prior to entrance into the TSE. This method generally yields a shorter fiber, while the direct roving feed produces long fibers and yields parts with higher structural performance.
Theadvantage of D-LFT mold is that it can reduce production cost by elimination of semi-finished products and logistical effort, and increase production flexibility.
