Plastic-metal compounds
(hybrid technology)

PRODUCT EXAMPLE: COIL BODY

The coil bodies are used in sensors to control fan systems. During the spraying process, the wire is fed endlessly from the roll and separated in the tool.

If necessary, the wires can be angled in the spray tool.

Technical data

  • Plastic: LCP Vectra E 130
  • Draht: Cu Sn6 / Square 0.38 x 0.38 galvanized
  • Spray tool: 4-fold
  • Gating type: Tunnel gate
  • Wire dimensions: min. 0.15 x 0.6 mm
  • Wire feeding: fully automatic
  • Wire bending: in the injection mold

PRODUCT EXAMPLE: CONNECTION BLOCK

The pins of the connection block are used for the automatic winding of the coil wires. The wires are fed endlessly from the roll and separated in the spray inge. The finished parts are stored nest-related.

Consistent quality measures guarantee ppm values of less than 50.

Technical data

  • Plastic: LCP Vectra E 130
  • Wire: Cu Sn6 / round 0.4 tinned
  • Spray tool: 4-fold
  • Gating type: Tunnel gate
  • Wire dimensions: min. 0.15 x 0.6 mm
  • Wire feeding: fully automatic
  • Wire bending: in the injection mold

PRODUCT EXAMPLE: PLUG INSERT

The plug insert is used as a connector in the sensor system. In an automatic manufacturing process, the gold-plated pins are inserted and automatically bent in the spray tool.

The diameter of the pins at the bend is 0.8 mm.

Technical data

  • Plastic: PA 6-3-T - Trogamit
  • Pins: Cu Zn gold plated
  • Spray tool: 2-fold
  • Gating type: Tunnel gate
  • Wire dimensions: min. 0.15 x 0.6 mm
  • Wire feeding: fully automatic
  • Wire bending: in the injection mold

PRODUCT EXAMPLE: GUIDE PIPES

The guide tube is used for air spring units/blocks. It is a plastic-metal composite part with injected sealing element. The article is characterized by its very high circular and surface quality as well as the exact shape of the sealing lip inside.

Technical data

  • Plastic: PPSU - Radel R 5000
  • Sleeve: Deep drawn stainless steel tube
  • Spray tool: 8-fold
  • Gating type: Tunnel gate

PRODUCT EXAMPLE: THREADED PIPES INJECTED

The injected threaded tubes are used as housings for sensors. They have a diameter of 8-12 mm and variable lengths.

In a semi-automated manufacturing process, the plastic is injected as a thin layer of approx. 0.25 mm on the inner wall of the pipe and forms a form-fitting connection with the metal.

With this technology, a wide variety of internal shapes can be realized, complex assembly processes can be saved and a high bond strength between metal and plastic can be achieved.

Technical data

  • Plastic: PA 12 - Grilamid
  • Twist part: Stainless steel
  • Spray tool: 4-fold

PRODUCT EXAMPLE: COIL BODY WITH CORE

The coil body with core is used in modern stepper motors. It is characterized by a very thin wall of 0.25 mm in the winding area as well as by extremely high pulling forces of the soldering feet of > 50 N.

In a fully automatic manufacturing process, 16 wires are cut off and bent off the roll in an 8-fold tool. The metal cores are overmoulded together with the wires and the finished parts are deposited nest-related.

Technical data

  • Plastic: LCP Zenite
  • Wire: Cu Sn6 / 0.5 x 0.25
  • Spray tool: 8-fold
  • Gating type: Tunnel gate
  • Wire dimensions: min. 0.15 x 0.6 mm
  • Wire feeding: fully automatic
  • Wire bending: in the injection mold
