MIM Tips for Designers

Unfortunately, it is impossible to avoid the rough surface at the gate. Normally, the gate roughness is convex, thus post treatment might be required.

Applying our 3D-MIM technology, it is possible to mass produce complex hollow design or micro size configuration.

Employing film or flash gate to eliminate weld line and improve the roundness tolerance.

Apply higher level of gate will minimize the polishing amount.

Unfortunately, it is impossible to avoid the rough surface at the gate. Normally, the gate roughness is convex, thus post treatment might be required.

Apply dummy boss in front of the feedstock confluence point to minimize the weld line defects.

Apply curve or chamfered corner to avoid demoulding or inhomogeneous problems.

Either eliminating the sudden huge thickness change or giving curve at the corner will minimize the problems above mentioned.

If the thick design is necessary, hollow out from the possible side. These hollows will help to avoid the sink mark or void. Also it helps minimize the unit price.
