?the?plastics,?automotive,?aeromotive?and?medical?industries,?amongst?others.?A?blade?shape?is?used?when

?there?is?only?a?small?surface?area?on?the?finished?part.?They?are?also?known?as?knockout?pins,?knock-out?

pins?or?KO?pins.?When?the?mould?is?opened,?the?pins?extend?into?the?mould?cavity,?push?the?part?out,?and?

then?retract,?allowing?the?mould?to?close?and?be?refilled.

Important?factors?to?consider?when?selecting?ejector?pins?are?corrosion?resistance,?

durability,?tolerance?and?tensile?strength.?Ejector?pins?can?be?made?with?a?variety?of?treatments,?which?

affect?the?hardness?of?the?pin.?By?choosing?the?right?ejector?pin?for?the?application,?the?lifespan?and?

durability?of?the?pin?will?be?enhanced.

Through?hardened?pins?are?good?all-purpose?steel?pins?that?are?heat-treated?to?be?uniformly?

hard?throughout?their?diameter.?They?are?often?used?for?injection?moulding?of?plastics?and?can?be?used?in?

cooler?moulding?environments?below?200°C.

Case?hardened?pins?are?nitrided?pins?that?are?suitable?for?die?casting?and?can?be?drilled?or?

tapped.?They?can?be?used?at?temperatures?above?200°C?and?are?quite?durable.?They?can?chip?when?

compared?to?through?hardened?pins?but?have?a?greater?life?expectancy?at?higher?temperatures.

Blackened?or?oxidated?ejector?pins?are?designed?for?extremely?high?temperature?working?

environments.?They?can?be?used?at?temperatures?from?about?600-1000°C.?These?ejector?pins?have?a?self?

lubricating?surface?coating?that?allows?them?to?be?used?at?these?high?temperatures.

Ejector?pins?can?be?further?enhanced?by?our?TiN?TiCN?HW?coating?and?other?coatings?which?

protect?them?and?make?them?more?durable.?These?coatings?work?by?reducing?friction?so?that?the?pins?

become?more?wear?resistant?and?the?ejection?of?the?part?becomes?more?consistent.
