Our manufacturing processes

Reliable materials for a flawless quality.

Printing

Plate making/dye preparation

  • an area dedicated to researching and defining hues by spectrometric analysis. Tinges are based on colour chart references (Pantone , RAL , NCS ... ) or from a customer sample,
  • the workshop where we produce the frames for screen-printing, fit in the silks, use direct coating or application onto a capillary film, photo emulsion stencilling, then dehazing[1] and screen reclamation after use. This gives us total control of the entire process. 

Degreasing/varnishing (metal substrates only)

  • 2 degreasing lines, including one with a built-in brushing process for sizes up to 700mm wide (550mm for the brushing process), 
  • 2 varnishing machines laying either coloured varnishes or base layers for screen-printing ink.

Silk-screen printing

  • 2 rotary screen-printing machines (uninterrupted printing process) : one to print conductive inks, the other one to print decorations. Thermal oven or UV drying process is built in each machine. 
  • 4 sheet-by-sheet silk-screen printing tables are used to work with metal and plastic before drying on-line or in ovens.

 

Cutting/Shaping

 

  •  2 plastic cutting (CO2 type) lasers are used for smaller scale production, as thicker and finishing cuts require dimensions smaller than +/- 0.3mm, 
  • 4 stamping presses equipped with bladed tools to cut plastics (adhesive, polyester, polycarbonate) less than 1mm thick.
  • various step by step and/or band feed mechanical presses equipped with matrix-punch tools to cut metal sheets or strips,
  • 2 embossing machines and 1 thermoforming press for embossed designs, and 3D tactile feel on polyester and polycarbonate products, 
  • 1 hydraulic press (also for embossing)
  • 1 folding press.

 

Lamination/Assembly

 

 

 

  • a machine to both laminate and cut materials thus combining up to 3 different materials and cut it all at the wanted size,
  • semi-automated lamination tables exclusively developed for PIM Industrie : our guarantee of an equal, standardised and impeccable quality of assembly for all various layers forming our keypads, 
  • highly dexterous operators for all manual offset operations such as fitting and strengthening the flexible flat cable (FFC), assembling very small units and components.

 

Components transfer

 

  • fully automated process,
  • machine stock allowing great flexibility in production organisation,
  • 1 SMD components transfer machine,
  • 2 dome-switch transfer machines,
  • 1 dual-purpose machine (dome-switches and SMD components),
  • over 1 million dome-switches and 350 000 LEDs mounted per year.

 

 

Electrical test and final inspection

 

  • every product dispatched undergoes a final inspection (functional testing of the keys and LEDs, loop resistance, short-circuit,...),

  • manual or automated tester,

  • production of a particular test template and cabling according to each product's specificities,

  • full visual check of all parts, and aesthetics before shipping.
