SMC mold
SMC is a mixture of polymer resin, inert fillers, fiber reinforcement, catalysts, 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 2,000psi 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 part-to-part repeatability. Trimning 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.

 

The advantage of SMC molding parts is as follows:
1,Good dimensional stability, including excellent thermal resistance.
2,Pigrnentable for molded-in color; best appearance with mold texture.
3,Excellent property retention in cold and hot environments.
4,Suitable for outdoor use in applications involving UV exposure and water.

 

BMC mold(Bulk molding compound mold)
BMC is bulk molding compound.
BMC mold used a thermoset plastic made up of a polymer resin, various inert 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
The material is available in a wide variety of colors.

GMT mold
GMT is Glass Mat Reinforced Thermoplasitcs, 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 1,300mm to 1,400 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 specific application and also can incorporate a decorative or functional surface laminated to one
side. GMT mold 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 furthe reduce weight and cost.

 

The advantage of GMT molding parts is as follows:
1,Utilization of regenerated
2,High production efficiency
3,Low Foaming pressure
4,Long storage period
5,Short shaping cycle

LFT mold (Long Fiber Thermoplastics)
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 compression molding. Most D-LFT systerrn, for injection or compression molding systems, feed glass roving (or other fiber) 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 longer fibers and yields parts with higher structural performance. Each approach uses different and specialized screw designs.

 

The advantage of FMT molding parts is as follows:
1,Reduced production costs by the elimination of semi-finished products and logistical effort
2,Increased production flexibility
3,D-LFTstrand with variable thickness for optirrized mold filling
4,D-LFT mold is mostly used in Automotive.

 

Carbon fiber mold
A Carbon Fiber is a fibrous carbon material having a micro graphite crystal structure made by fibrillation of Acrylic resin, a well knowntextile material, or from oil/c then by being given a certain in heat treatment.
Carbon fiber mold has been used widely in many kinds of fields, such as plane, rocket, golf driver, automobile, construction and so on.
