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. 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.

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.

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.
GMT is Glass Mat Reinforced Thermoplastics, a kind of sheet molding compound with fiber reinforced thermoplastic. It is produced on huge laminators, using a thermoplastic resin and one or more forms of reinforcement. The process yields a lightweight, partially consolidated, semifinished composite in sheet form. Most forms are produced to 1300mm to 1400 mm widths. However, some newer forms are made to greater but proprietary widths. The sheet stock may be cut to size to suit placement in the tool for a specific application and also can incorporate a decorative or functional surface laminated to one side. GMT mould makes possible the production of large parts with low tooling costs and fast cycle times via compression molding. The potential for parts consolidation presents the opportunity to further reduce weight and cost.
The advantage of GMT mould parts: utilization of regenerated, low forming pressure, long storage period, short shaping cycle, high production efficiency.
