How is BMC molded?

Usual method of molding BMC is by compression molding. BMCs can also be injection molded in much the same way as other plastic compounds using ram, ram-screw, and, for certain BMC mixes, conventional reciprocating screw injection molding techniques (Chapter 4). The usual BMC plastic uses thermoset polyester.

What are bulk molding compounds (BMCs)?

Also called dough molding compounds (DMCs), bulk molding compounds (BMCs) are mixtures usually of short 3 mm to 3 cm (⅛ to 1¼in.) glass fibers, plastic, and additives similar to the SMC compound. This mixture, with the consistency of modeling clay, can be produced in bulk form or extruded in rope-like form for easy handling.

What makes BMC A good mold?

BMC is extremely lightweight and strong with the ability to resist chemicals, weather and more. Plus, it has the ability to flow into small details in the mold, which allow for a more detailed component that are cost effective.

What is a Toray BMC?

Toray BMCs are engineered for the success of your satellite, aerospace, and high performance applications. Designers turn to Toray’s chopped fiber thermoset bulk molding compounds to create complex composite assemblies quicker, less expensively, and with higher performance ratings.

Why should you use chopped fiber thermoset bulk molding compounds?

Designers turn to Toray’s chopped fiber thermoset bulk molding compounds to create complex composite assemblies quicker, less expensively, and with higher performance ratings. Additionally, replacing metallic assemblies with lightweight chopped fiber compression molded BMC parts can reduce weight by more than 40% over aluminum parts.

How does a BMC injection molding machine work?

In the injection molding process, the cold BMC rope is mechanically stuffed into the feed section of an injection molding machine. The plasticating screw of the injection molding machine pulls the rope into the preheated barrel and moves it forward as it turns about its own axis inside the barrel.
