SMC -The main process
for molding SMC material is Compression molding. The film is stripped off and the material
is cut into suitable pieces. These are collated into piles of material, which are called the charge. This is positioning in the
mould tool. Heated moulds are used and a compression pressure is applied. The base resin
being a thermosetting material cures and hardens. The part is ejected. Any flash is
trimmed by the operator.
SMC process: Manufacture of SMC is a
continuous in-line process. The material is sheathed both top and bottom with a plastic
film. A Paste is prepared comprising resin, styrene, heat activating catalysts, inert
fillers, release agents and thickeners The paste is spread uniformly onto the bottom film. Chopped glass fibres are
randomly deposited onto the paste. The top film is introduced and the sandwich is rolled
into a pre-determined thickness. The sheet is allowed to mature for 48 hours.
DMC
And SMC Moulding Materials
The materials are widely known as Dough
or Bulk Moulding Compounds (DMC or BMC). In sheet form they are known as Sheet Moulding
Compound (SMC).
Raw Materials Used
Both DMC and SMC use similar raw
materials. |

Base Resins
DMC (BMC) and SMC materials are available in various
grades and types. Three base resin systems are in common use.
Orthophthalic Generally used for lower cost and lower performance applications.
Isophthalic Has good heat, chemical and toughness properties
Maleic Used to provide superior surface finishes. |
How The Materials Are Molded
DMC --Two basic
moulding processes are used to mould DMC, Compression Moulding and Injection Moulding.
Smaller components are usually made by the injection moulding process. Larger components being
compression (or transfer) moulded. In Injection moulding the material is loaded
into the barrel of the machine. A stuffer plunger forces the material into the screw area
of the machine. The screw and barrel are heated to pre-warm the material. The material
flows into the mould via runners. The moulds are heated which cures the resin content and
hardens the now moulded part. When Compression moulded, the operator pre-weighs a
charge of material and places it into the open mould. The heated mould and pressure flows
the material into the cavity. The heat cures the resin, which hardens the moulded part. A
derivative of compression moulding is Transfer moulding. The charge of material is
placed in a chamber within the tool. The mould is closed and a ram acts on the chamber
forcing the material to flow via runners to the cavity of the tool.
Applications
DMC & SMC components are
hard, rigid mouldings with excellent electrical resistance properties. They have replaced
glass and ceramics for insulating applications. The manufacture of large flat panel type
mouldings, with excellent strength, are used for commercial vehicle body parts. |
