BMC/DMC making manhole covers Sigma Mixer

sigma mixer for hotmelt adhesive

Application and introduction

Composite BMC/DMC machine is mainly used for producing BMC for composite materials use . BMC is a semi-dry manufacturing of glass fiber reinforced thermo setting products of the molding intermediate material, from unsaturated polyester resin, low shrinkage / low profile additives, initiators, internal release agent, mineral filler, etc. mixed into a paste, Adding thickener, coloring agent, etc., with different lengths of glass fiber, in kneader in the mixing, the process of thickening, and ultimately the formation of mass-like intermediate material can be used for molding and injection molding. BMC machine now is widely used on making BMC used in Electric appliance, motor, radio, meter box, chemical machinery, construction and so on.

How It work

The BMC production line is consist of many parts , The important is the mixing part, Sigma mixer / kneader is the best choice for BMC/DMC, Because of its high viscous and its bulk state ,After the mixing ,the BMC can be shaped by different method ,like mold ,injection ,and so on ,normally injection is the most choice, After the BMC feeder forced into the BMC cartridge, and then through the screw to the barrel in front of the mold, and then injected into the mold cavity curing a process Then it became different shape.

Other advantages

BMC production line is with high efficiency and with very easy operation and assemble .Low energy cost and less manpower needed is an specialized production line design for the BMC/DMC material.

The production capacity is customized ,and materials of the production line can be optioned by Stainless steel 304 and 316.

Abster Sigma  mixer provide with design and drawing of the production line and also provide with help installation and operation in customer factory.
