Sheet Molding Compound Machine 

Sheet molding compound (SMC) is a process as well as reinforced composite material. The composite is a “ready to mold” glass and other fiber reinforced polyester resin material mainly used in compression molding. The compound is produce in rolls and zigzag winding shapes, SMC compound is manufactured by uniform distribution of chopped strand glass or other fibers in required proportion by weight over moving carrier film having layer of resin compound from upper and lower doctor box. 

 Mix matrix is then impregnated by passing through upper and lower set of rollers with control pressure and after final impregnation compound sheet is collected at the winder either by roll winding or zig-zeg winding for further storage and use. 

 Compound sheet can be produce with following variables,  

• Compound sheet width and thickness
• Compound sheet unit area weight
• Percentage of glass / other reinforcement in compound sheet With different strand length as per product requirement

 SMC Machine Specifications:  

• Compound Width : up to 1200mm
• Compound Weight : 2.5 - 6.0 Kg/m²
• Glass Content : up to 50% * (Using Double Chopper Head) With Strand length 1/2” – 2”
• Electrical Power : 6.5 kW. (Connected Load)
• Compressed Air : 4-6 CFM at 70-80 PSI Pressure
• Machine Speed : 2 – 8 mtr/min.

SMC Machine Features:

Precision tubular machine structure with epoxy primer and PU paint
Precision machine components with required protective coating
Life lubricated gear reduction drives
PLC, HMI, AC Drives for machine operation and control

Advantages

Compared to similar methods, SMC benefits from a very high volume production ability, excellent part productivity, it is cost effective as low labor requirements per production level is very good and industry scrap is reduced substantially. Weight reduction, due to lower dimensional requirements and because of the ability to consolidate many parts into one, is also advantageous. The level of flexibility also exceeds many counterpart processes.
