FAQs About Industrial Plastic Fabrication
Q1: What’s the difference between plastic molding and fabrication?
Molding refers to forming shapes from molten plastic (e.g., injection molding), while fabrication may also involve machining, bending, or welding plastic sheets.
Q2: Can custom plastic parts replace metal components?
Yes. Engineering plastics like PEEK, Nylon, or PC are now used to replace aluminum or steel in many load-bearing or chemical applications.
Q3: How can I validate part quality before mass production?
Use samples, PPAP reports, FAI (First Article Inspection), and SPC (statistical process control) to confirm quality.
Q4: What is the typical lead time for industrial OEM plastic parts?
Tooling may take 3–5 weeks; sample and production parts typically ship in 1–2 weeks post-tooling.
Q5: Can plastic fabricators offer hybrid assemblies with metal inserts?
Yes, advanced providers like Prime Custom Parts specialize in overmolding, insert molding, and post-molding assembly.
