Plastic injection molding from a single source — from idea to packed pallet

BKM emerged in 2023 from the acquisition of WS System's plastics division — with an experienced team, proven processes and a customer base that has relied on consistent series quality for years. Today, around 15 employees in Stuhr near Bremen produce more than 10 million parts per year for over 200 industrial customers across Europe.

Tooling, injection molding, insert overmolding, finishing, assembly and logistics interlock at BKM — one contact person owns your entire process. That shortens paths, avoids interface losses and keeps deadlines predictable.

  • Own toolmaking
  • Tooling takeover & management
  • Horizontal machines 5–1,000 t, vertical insert machines 50–400 t
  • ISO 9001 · REACH · RoHS
  • In-house logistics, partly with our own vehicles
  • Project handling in German and English

How we work

From first conversation to running production

Six steps, one point of contact: this is how your inquiry becomes a series part you can rely on.

  1. Inquiry & analysis

    We assess part, material and quantities — and tell you honestly what's feasible.

  2. CAD & prototype

    In-house design, 3D-printed prototypes for fast iterations before toolmaking.

  3. Property analysis

    Impact resistance, fire behavior, durability — tested before money goes into the mold.

  4. Toolmaking

    Precise series molds, built for service life rather than the quick price.

  5. Series production

    Fully automated production with in-process metrology, ISO 9001 certified.

  6. Logistics & shipping

    Freight and shipping from a single source — partly with our own vehicles, Europe-wide.

Contract manufacturing

Three services, one point of contact

Tooling & production

We take over existing tooling and ongoing production — seamlessly, without any loss of quality.

  • Mold inspection and run-in process before series start
  • Seamless takeover of running series
  • Clamping force range 5 – 1,000 t for almost any mold

Finishing

Surface and functional finishing of plastic parts to your technical specifications.

  • Surface finishing to technical specification
  • Ultrasonic welding for permanent joints
  • Functional testing as part of the process

Assembly

Assembling individual plastic parts into a finished product, including quality assurance.

  • Fully automated assembly directly at the machine
  • Manual final assembly for complex units
  • 100% inspection available for safety-critical parts
