Compression Molding - SMC & BMC

For the materials that are used in the compression molding process, SMC (Sheet Molding compound) and BMC(Bulk Molding Compound) are common. SMC & BMC are a blend of fillers, resin, and reinforcement that is molded to form a useful component. To know more visit us.

  1. COMPRESSION MOLDING - SMC & BMC www.en.wl-upr.com

  2. There are certain processing techniques that are used to manufacture composite components and compression. Such include heat and the application of pressure to create components that are robust and have relatively low cycle times.

  3. For the materials that are used in the compression molding process, SMC (Sheet Molding compound) and BMC(Bulk Molding Compound) are common. Such materials consist of glass fiber reinforcing fillers, strands, pigments, additives, and lastly resin in different forms.

  4. SMC & BMC are a blend of fillers, resin, and reinforcement that is molded to form a useful component. Typically, SMC is a sheet made up of resin reinforced with glass fibers. It is then converted into mold and compression molded. BMC is a blend of uncured resin reinforced with glass fibers that are injected into the mold.

  5. As opposed to SMC, It is not essential to recourse to maturation and as a result, BMC formulations contain more filler content. Usually, the filler is calcium carbonate and the resin can be polyester, epoxy, urea, vinyl ester, melamine, or polyurethane. With reinforcement content varying from 10-20%, BMC ideally suits injection molding and compression.

  6. When it comes to distinguishing the features of SMC and BMC, the former possesses long fiber length and higher fiber content. Its rich characteristics lead to better strength, both tensile and flexural. SMC-made components are widely used in trucks, passenger cars, agricultural machinery, building façade panels, and electrical cabinetry.

  7. Due to smaller fiber length and lower fiber content, injection molding with BMC can be made to fill inner cavities and not so thicker parts. BMC- made components find their utilization in appliance components, auto engine throttle bodies, and headlamp reflectors.

  8. The molding process ideally suits the formation of products that need a few common characteristics including unique design features, low unit cost, lightweight with excellent strength-to- weight ratio, and excellent acoustic, and thermal performance.
