Simulation Technology for Injection & Molding

Foresee Technology has a rich experienced engineering team who provides molding simulation and analysis to predict future manufacturing issues at the design phase, which anticipates the majority of defects in PIM components occurring during injection molding, also automatically generates optimized tool and designs by analyzing multiple variations of gate location and type.

Material Development

PIM offers greater design freedom than many other production processes by freeing designers from the traditional constraints associated with stainless steel, low alloy, tool steel, soft magnetic alloy, special alloy, ceramic and others. We offer expertise in research and material development.

Cost advantages

There are a number of factors during our designing that can reduce or eliminate the need for secondary machining after sintering, which will reduce overall component cost. It’s always our aim to peruse a cost benefit solution complying with customized


There are a range of materials that can be processed along with specified properties when use PIM technology, followings are the main process steps introduction of PIM.

1, Feedstock

Fine powders are mixed with thermoplastic or wax binder in a precise recipe. The compounding process creates a homogenous feedstock that can be injection molded.PIM can achieve 95% – 98% of theoretical density, which means we can achieve tight tolerance and produce small and complex parts in high volumes.

2, Molding

The equipment and technology of Powder Injection Molding are similar with Plastic Injection Molding. Feedstock is put into injection machine, heated, melted and injected into mold cavity under high pressure. After cooling down, green parts form, and eject from mold. Mold can be designed into multiple cavities to increase capacity. Mold cavity dimensions should be about 20% larger than the finished product dimensions, to make up the shrinkage in sintering. The shrinkage ratio of each material is accurate and certain.

3, De-binding

Binder removal (de-binding) involves several steps to get “green part” removed from the binder. Most of the binders are removed before sintering, while there are always still some binders existing for holding the metal powder particles together. Once de-binding completed, the component is referred to as “brown part”.

4, Sintering

The sintering process leads to the elimination of most of the pore volume formerly occupied by the binder. The “brown part” reaches near the melting point of the material during sintering, and becomes to a solid part, giving its final density and strength.


Due to the big shrinkage ratio in sintering process, some parts’ geometric profiles may deform. Shaping process can bring the profile back under high pressure with designed shaping tooling.


The tolerances of sintered part can be ±0.1~0.3% of related dimensions.CNC process can make sintered part achieve higher accuracy.

7,Surface Teartment

According to customers’ needs, some products may need surface treatment after sintering. The surface treatment we can do includes polishing, sand-blasting, plating, epoxy coating, etc.
