Look at total cost of ownership - often people focus on minimizing one area of cost (for example tool cost) that jeopardizes the end product. Lowest cost comes from the right combination of part design, material selection, tooling, manufacturing process.
~Bill M, Senior Mechanical Engineer, Round Rock, TX
Never compromise on the quality of raw materials if you manufacture standard products. Do not change the source of raw materials as much as possible to achieve consistency.
~NANDA KUMAR NARAYAN, Technical Support, Bangalore, India
Understand the application to the fullest. Temperatures, Impact required, wall thickness, weatherability, how it is used, useful life, chemical contact.........
~John H, General Corporate Mgmt, Manchester, NH
3D image in brain is important. The plastic material has or works with bigger deflection than metals. So any idea should be based deflection not force.
~Hiroshi Shimizu, Engineeering constultant, Kawasaki Kanagawa, Japan
Give enough attention to polymer class selection before selecting the right material within a polymer class (Stage-wise focusing from broad to narrow)
~Niels S, Engineering Consultant, Nijmegen, Netherlands
Try to use mostly recycled polymers with some additives to improve desired strength and hence we can reduce cost and waste material piling up.
~Sriram V, Consultant, Chennai, India
Define the requirements of the part before you pick a material or start a design. Try to stay away from localized fraternizing.
~Gene Jackson, Engineering Consultant, Deer Park, WA
More than one typical property must be considered when selecting a polymer, and that pricing can be very volatile.
