One assembly.
Every interface matters.
Start with the processing application, compare component families, then organize the material and drawing information for a focused technical discussion.
Processing applications
Choose the production context first. Pipe, profiles, foamed sheet and filled blends ask different questions of the same component family. Use these application routes to prepare a focused screw-and-barrel review.
Explore the guide ↗02Materials & technical review
Material selection is a comparison of construction, operating context and evidence. Start with what is known about the part and the compound, then identify what a proposed treatment must demonstrate.
Explore the guide ↗03Quality & project evidence
Quality requirements become useful when they can be traced to a part, a drawing and an acceptance record. Use the project checklist to define the evidence needed before comparing components.
