Sprung core pins: |
1.Material: flexible steel |
2.Have high degree of precision. |
3.Using bottom to release the elasticity angle, like standard pins,through ejector board to realize its function. |
4.Cooperate with guide bush,prevent the pins and mold board from friction between long-term usage. |
5.To reduce times of mold finishing. |
6.The screw up to 0.75mm,It also can be fine adjustment. |
Sprung Core Series:
1. PW Sprung Core , Material : 1.8159, Hardness: 45+/-3HRC
It’s made from spring steel , release elasticity at bottom as standard ejector pins, and fulfill it’s function by eject plate.
2.PW Sprung Core , Material : 1.8159, Hardness: 45+/-3HRC
It’s made from spring steel, release elasticity at bottom, with guide bushing to prevent the damage from long time’s friction between it and mode plate.
3.PF Sprung Core, Material: 1.2101, Hardness: 45+/-3HRC
Because the contact surface is parallel with ejector plate, the thickness of release elasticity from bottom’s smallest area is just 4mm, and a new characteristic of this product:
first eject then elasticity from the bottom.
4.MP Sprung Core, Material: 1.2101, Hardness: 45+/-3HRC
Apply to release elasticity from bottom, the ejector device can adjust to required eject height in advance, easy to install, and keep 90° with devided surface when install it.
5.ED Sprung Core, Material: 1.2101, Hardness: 45+/-3HRC
It’s function is same as sling ejector pin MP, just the released elasticity is smaller from its bottom, easy to installed,
just has only one installation aperture, the height is easy to adjust, with smaller process tolerance.
6.EE Sprung Core, Material : 1.2101, Hardness: 45+/-3HRC
Apply to release elasticity from bottom, the ejector device can adjust to required eject height in advance. Easy to install,
and keep 90° with the devided surface when install it.
