Ejector Pins with cylindrical head / Similar to DIN ISO 6751 A.

Range of application:

Injection moulding and die-casting with high thermal conductivity.

Advantages:

• better product quality because of better temperature

distribution

• reduced time of the design cycle

• long service life design for optimum friction

• higher thermal conductivity than the WS or WAS pins

The dimensions are shown in the table.

Material:

Special copper alloy - beryllium-free

Material properties:

• 6 times higher thermal conductivity than conventional tool steel

• Similar heat expansion as with tool steel

• Corrosion resistance

• Very good for processing (milling, polishing, etching, eroding)

• Protective coating possible

Technical data:

• Tear strength Rm: 650-750 N / mm 2

• The yield strength (0.2 % creep limit): 500-650 N / mm 2

• Specific heat capacity: approx .: 380 J / kgK

• Thermal conductivity at 20 ° C / 68 ° F .: about 200 W / mK

• The coefficient of heat expansion of 20-200 ° C: 0,000016 K

• Softening point: 420 ° C / 788 ° F

Finish:

Ground shank, hot forged cylindrical head.

Note: In the processing of plastics, reinforced with fiberglass, protective coating is recommended to reduce wear and tear.
