TOOLS FOR COLD HEADING MACHINES
TMA KNOCK-OUT PINS (EJECTORS)
KO Pins, Ejector are used to eject completed parts from die moulds and are commonly used in the fastener industry. They are also known as knockout pins, knock-out pins or ejector pins. Ejection is performed with great effort, therefore, as a rule, this tool is made of high strength steel. Ejectors are available in various sizes and shapes, such as round, conical, straight and cylindrical. KO pins are widely used in heading equipment, in conjunction with other tools such as stamps of headers, rolling dies, and stripping dies.
The important factors in choosing of ejector should include the degree of corrosion resistance, durability and tensile strength. Another important factor is the temperature at which the instrument will be used. Temperature conditions affect the strength and durability of the ejector. Plating can improve the life of the ejector and make it more durable. Coating reduces friction, which also makes the ejector more chemically inert and stable.
Material: SKH9 (M2) Hardness: HRC 63±1°C
Application: widely used in heading equipment, in conjunction with other tools such as stamps of headers, rolling dies, stripping dies.
