Post Process
——————————————————————————
Cosmetic Base Post Process information are Subject to Material & Requirements | ||
CNC Post Process | Some complex shape product need CNC/ Machining during the post process,this could be addition but it is not important that every part must need it. This depend on part's requirements. | |
PVD | Possible to get the different PVD color such as White,Black,Golden,Brown,Green,Blue ect…… | |
Surface Finish | MIM product are good to get the required surface finish such as hair line surface finish,brush finish,sand blast mirror surface finish ect | |
Plating | MIM material can be readily plated or surface treated with standard process used on wrought material with no need for special surface preparation.Examples of some plating and surface treatments offered are: electrolysis nickel,chrome,zinc,chromatic,nickel teflon,black oxide and passivisation. |

Process Description
——————————————————————————
Metal powder of fine partical size is mixed with thermoplastic polymer to form a mixture of ingredients konwn as feedstock. The feedstock made into pellets and fed into the moulding machine. | ||
The feedstock is heated to melt the plastic and molded to the desired shape. The moulded parts is known as green part. | ||
The binder is removed thermally by heating to around 400 degree centigrade from the green part,by a debinding process. The debound parts called as brown parts and is brittle and porous. | ||
The brown parts is heated to more than 1200 degree centigrade,in the finale sintering process allowing the part into a dense solid with the elimination of pores. The sintered density is wimilar to a casting at about 98% of theoretical. |

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 reduction when tooling cost and raw material cost been considered.
- Geometry complex
PIM technology is specially profit for component has holes,slots,ribs,protrusions,and multiple features.The typical max outlet is range from 25mm to 35mm,wall thicjness 0.08 to 10mm.
Several aspects of the 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:
Allowed design features
- Axisymmetric,nonsymmetrical,prismatic,square,and freeform features
- 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 another
- Undercuts, grooves,slots,depressions
- External teeth,external or internal threads
- Knurled and waffle surfaces
- Part number or identification logo created by the mould
Features to avoid
- Inside closed cavities
- Undercuts on internal bores
- Very shape corners or design-desired radius greater than 0.05mm
- Long pieces without a draft or taper to allow ejection
