Choosing The Right Material

August 17, 2018

When choosing the right type of material, it is important you pick the right one according to the application and industry to avoid future drawbacks. Design requirements, material criteria and evaluating potential materials are important to  find the ideal material. 

 

 

Design Requirements
Keeping in mind the following requirements is extremely important.

  • Government regulation

  • Performance

  • Size, weight and shape

  • Cost

  • Industry standard

  • Reliability

 

Material Criteria

    What is the end goal for the product being machined? Any materials that cannot support the finished goal should be taken off the table immediately.

 

Evaluating Potential Materials

    Finding the right material that fits requirements is important but exceeding those requirements is unnecessary. A major waste in lean manufacturing is using higher grade materials than necessary. Going through material testing may be your best bet to find the ideal material for the proposed application. In the prototype stage, it is always beneficial to produce prototypes in various materials to find the best fit.

 

Below find a few of our most commonly used material: 

Stainless Steel
