Designing for Metal Injection Molding: A new online resource for designers and end-users
April 2, 2009
PIM International has just launched a new free-to-access online resource for designers and end-users of metal injection moulded components.
Effective guidelines are presented that highlight key considerations that are necessary when developing a component for MIM production.
As this online resource clearly demonstrates, the greater the understanding of the MIM process that a designer has, the greater the chances of successful adoption of MIM technology.
Although prepared specifically for metal injection moulding, much of the information presented will also be of use to anyone also considering ceramic injection moulding (CIM).
Information is divided into the following sections:
MIM: A guide for designers and end-users
The importance of designing for MIM is highlighed, not only improving the chances of successful production but also bringing higher process yields, lower costs and faster processing.
When is a part suitable for metal or ceramic injection moulding?
Key questions are answered, from realistic production volumes to the advantages of design complexity, plus how is MIM different to plastic injection moulding, and what materials can be processed?
Optimising your design for MIM
From desirable and allowed design features to features that have to be avoided, plus the importance of size limitations and the benefits of simple design modifications.
Further design considerations
The impact of sintering on dimensional tolerances, advantages of the MIM process and a table of typical and best possible dimensional tolerances.
MIM material options and component properties
Includes alloy types, popular materials, fatigue strength and fracture toughness, corrosion resistance and opportunities for improved wear performance.
Table of tensile properties of representative MIM alloys
Typical room temperature tensile properties of representative MIM alloys.
Cost, delivery and flexibility
Tooling costs and the influence of feedstock prices are addressed and a comparison of costs between two differing vendors is presented.
Overview: Key criteria for selecting MIM technology
A summary of MIM’s key strengths and advantages, plus a review of essential advice for end-users. ‘Metal injection moulding leads to outstanding success when the design anticipates MIM fabrication and invites expert participation.’
