PIM comparisons with other net-shape forming technology

Feasibility of powder injection molding technology is up to the other competitive processes. In any project, there are two steps in the competition. First step is to filter based on the processing capacity: what kind of technology can be used to form the desired characteristics and properties? The second step is based on the cost of competition: the expected production volume, filtered through the first step of forming process of which one the lowest cost? If the first step does not meet the technical requirements, the costs you don’t need to take into account. Process capability is always the first obstacle, but the cost was always off the core problems.

First of all is to identify whether PIM used in the main processes. This means that PIM can be used to make the original shapes of the parts. Different from the machine, PIM, as subsequent processing efficiency is not high. Then judge whether the product has a three-dimensional features discrete parts, different with wire, cable, sheet, tube or plate, these products at least is longer in one dimension, continuous process for production of the most appropriate. Next needs to be considered is the economics of production volume, is the quantity of the order, is used to determine cost of tooling and equipment. Realistically speaking, required over 5,000 pieces of the order.

Due to begin PIM needs high tooling cost, when production is low, the machining is suitable. For the parts that have strict tolerances, first using PIM components, then using finishing precision to control tolerances. In order to compete successfully with other craft, PIM must at a minimum cost, under the premise of meeting the project requirements, PIM application materials, parts, product strength, shape complexity, surface roughness has the advantage of size and productivity.
