PIM Parts Design guideline

Fast Assessment of a part suitable for metal or ceramic injection molding based on

Cost-effective

Normally yearly demand over 20k and typical weight from 0.02-50g will be highly cost been considered.

PIM tcehnology is specially profit for component has holes,slots.ribs,protrusions,and multiple features.The typical max outlet is range from 25mm to 35mm,wall thickness 0.08 to 10mm.

Several aspects of PIM component design improve the ease of manufacturing,,and there are a number of design features that should be avoided.These are categorized as follows:

Axisymmetric,nonsymmetrical,prismatic,square,and freeform featues

Cantilever and nonsymmetrical shapes

Stiffening ribs and locator features for assembly

Protrusions,bosses,and studs

Most hole shapes are allowed,including blind and through holes

Holes at angles to one anther

Undercuts,grooves,slots,depressions

External teeth,external or internal theeads

Knurled and waffle surfaces

Part number or identification logo created by the mould

Features to avoid as follows:

Inside closed cavities

Undercuts on internal bores

Very sharp corners or edges-desired radius greater than 0.05mm

Long pieces without a draft or taper to allow ejection
