Working with MF Moulding Compound D704-T10
Is MF Moulding Compound easy to machine?
Drill, trim and tap with sharp carbide or diamond tooling at high speed and low feed; the cured resin and mineral/glass fillers are abrasive and the material chips at unsupported edges.
Can MF Moulding Compound be welded?
Not weldable or re-meltable — thermoset; join by mechanical fasteners, moulded-in inserts or adhesives (epoxy, cyanoacrylate) after abrading the glossy skin.
Can MF Moulding Compound be formed, bent or molded?
Compression, transfer or thermoset injection at 145–175 °C mould temperature with 20–40 s/mm cure; pre-heat or preform the powder, vent/breathe the tool to release condensation water, and allow 0.5–0.9 % shrinkage (0.1–0.4 % for glass grades).
What surface finishes work on MF Moulding Compound?
Comes out of a polished tool with a high-gloss, colour-fast surface needing no paint; deflash by tumbling or blasting, and avoid plating — decorate instead with melamine overlay foils or in-mould paper.

Is MF Moulding Compound D704-T10 easy to machine?
Not especially — machinability is rated poor (26/100, worse than 90% of polymer grades). Drill, trim and tap with sharp carbide or diamond tooling at high speed and low feed; the cured resin and mineral/glass fillers are abrasive and the material chips at unsupported edges.
Can MF Moulding Compound D704-T10 be welded?
Not readily — weldability is rated not recommended (0/100). Not weldable or re-meltable — thermoset; join by mechanical fasteners, moulded-in inserts or adhesives (epoxy, cyanoacrylate) after abrading the glossy skin.
What surface finishes work on MF Moulding Compound D704-T10?

What is the maximum service temperature of MF Moulding Compound D704-T10?
MF Moulding Compound D704-T10 is rated for continuous use to about 165°C (329 °F), and briefly to 150°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
