Quality Assurance at JBRplas

Quality at JBRplas is built into every stage of the manufacturing process — not inspected in at the end. Our ISO 9001:2015 & 13485:2016 certified quality management system defines the standards, procedures, and responsibilities that govern every project from initial RFQ to final delivery.

Quality System Overview

Design Phase

  • DFM Review — documented Design for Manufacturability analysis with written report for every project
  • Moldflow simulation — fill, warp, and cooling analysis before tooling begins
  • Design review — formal engineering sign-off before mold machining starts
  • Customer approval — 2D and 3D mold design submitted for customer review before machining

Mold Manufacturing Phase

  • In-process dimension checks — CMM verification at critical machining stages
  • Steel hardness verification — Rockwell hardness tested and recorded per mold component
  • Assembly inspection — mold assembled and verified against design dimensions before trial
  • Trial documentation — all T1 / T2 process parameters recorded and retained

First Article Inspection (FAI)

Every new mold program goes through a documented First Article Inspection before production approval:

  • Full dimensional report (all drawing dimensions measured and recorded)
  • Visual inspection against cosmetic standard (approved sample or written standard)
  • Material certificate — resin grade and lot traceability
  • Process parameter record — injection settings at approved sample production
  • Customer sign-off on first article samples before production release

Non-Conformance Management

When a non-conformance is identified — whether detected internally or reported by a customer — JBRplas follows a structured corrective action process:

  1. Containment — immediate sorting, quarantine, and shipment hold if applicable
  2. Root cause analysis — 8D or 5-Why methodology within 48 hours
  3. Corrective action — process or tooling correction, implemented and verified
  4. Preventive action — update to control plan, FMEA, or operator instruction
  5. Closure — written CAPA report provided to customer

Our customer-reported defect rate for established programs is below 0.3%.

Supplier Quality Management

The quality of our output depends on the quality of our inputs. JBRplas maintains an approved supplier list for:

  • Steel and mold component suppliers (inspected per certificate)
  • Resin suppliers (approved brands only; lot certificates required)
  • Surface treatment suppliers (plating, painting, texturing)
  • Bought-in standard components (springs, fasteners, connectors)

All approved suppliers are audited annually.

Clean room production and injection molding fundamentals are covered in dedicated guides: when injection molding needs a clean room, what injection molding is and what it costs, and medical molding compliance documentation.
