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 ke motsoako oa resine ea polymeri, kenya li-fillers, fiber reinforcement, catalyst, pigments, stabilizers, li-release, le li-thickeners. Ho hlahisoa ha SMC ke ts'ebetsong ea ts'ebetso e tsoelang pele.
This process produces high strength, complex parts in a wide variety of sizes. Matched metal dies are mounted in a hydraulic molding press. The material 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.
Compression molded fiberglass parts are characterized by net size and shape, two excellent finished surfaces, and outstanding parts-to-part repeatability. Trimming and finishing costs are minimal.
In-mold coatings and vacuum system in the tool are available to improve surface paint ability, eliminating the need for primer.
Color compounds can be customized.

3. Excellent property retention in cold and hot environments.
4. Suitable for outdoor use in applications involving UV exposure and water.
BMC mold used a thermoset plastic made up of a polymer resin, various insert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous. It is highly filled and reinforced with short fibers.
BMC is available in bulk bags as well as slug form. The mixing 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. The process 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. The material 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.

LFT is bulk molding material that feature continuous fiber filaments running the full length of the pellet allowing these materials to exhibit simultaneous improvements in strength, stiffness, and impact resistance over a wide temperature range.
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.
The advantage of D-LFT mold is that it can reduce production cost by elimination of semi-finished products and logistical effort, and increase production flexibility.
