Why BBF for Machined Plastics & Metals

  • Deep plastics expertise. Since 1994 we’ve specialized in high-purity plastic systems and equipment—so we understand chemical compatibility, stress-cracking, and surface finish.
  • Now with SST capability. Light-to-medium duty stainless (304/316L) and aluminum machining for brackets, adapters, and interface hardware.
  • Tight-tolerance work. ±0.005” typical; tighter on request.
  • Responsive lead times. Prototypes in days; production in 2–4 weeks.
  • Design-for-manufacture help. Send a model or sketch—we’ll suggest material and geometry tweaks to save time and cost.
  • One floor, end-to-end. Machining, bonding, bending, and assembly under one roof.

Industries: Semiconductor, electronics, chemical processing, water treatment, life-science labs, and general industrial.
