Overview
Have you seen our comprehensive range of ejector pins yet? Through-hardened ejector pins with or without DLC coating, nitrided ejector pins with an oxidation coating, ejectors from HSS as well as contour core pins in various materials are all available from stock.
We would like to inform you about our range of ejectors and core pins below. In addition, you will receive details about the materials and the different variants.
Ejector configurator
Don't waste any time thanks to our ejector configurator.
- Direct ordering of ready-to-use ejectors without enquiry process
- Simple and intuitive handling directly in our digital catalogues
- CAD data of your individual ejector available immediately after configuration
Nitrided-oxidation coated ejectors
- Suitable for applications in die casting and injection moulding
- Oxide layer reduces static and sliding friction
- High corrosion resistance through oxide layer
- Good dry-running properties
Ejectors with DLC coating
- Increased corrosion resistance and service life
- Guaranteed interchangeability through exact tolerances
- Excellent dry-running properties suitable for use in cleanrooms
- Minimised wear thanks to excellent sliding properties
- Leave no stains on plastic parts
Ejectors from HSS
- Suitable for high mould temperatures thanks to best high-temperature resistance
- High durability through low wear and high hardness ~64HRC
- Increased service life when used with plastics with a high glass fibre content
Ejector pin stainless steel
- Especially for use in cleanrooms
- Optimally suited for processing aggressive plastics
Ejectors with anti-twist lock
- Ejector pins with precise anti-twist lock for exact positioning
- The anti-twist lock already provided on the head enables cost-effective production of contour ejectors
- Two different anti-twist locks with different dimensions are available from stock
Ejector sleeves
- Hardened ejector sleeves made of 1.2210
- Nitrided ejector sleeves made of 1.2343
Ejector sleeves, stepless
The stepless transition from the clearance hole to the guiding hole prevents damage to the ejector and core pins. This can minimise wear, especially in applications where it is necessary to move completely out of the guiding hole.
Blade ejectors
- Ideal for wire cut openings
- Available with extra long blade for large ejector strokes
- Ready to use, high-precision blade ejector pins with 2 or 4 angle radii - with or without extra long blade
- Blade ejectors with radii also available with DLC coating
Ejector pin for ventilation
- Fast, targeted ventilation of the cavity via the ejector pin
- Can be cut to required length thanks to ventilation surfaces along the entire shaft length
- Optimal guidance of the ejector due to g6 tolerance on the shaft
Thanks to the ventilation surfaces along the entire shaft, the cavity can be quickly and specifically vented via the ejector pin. The ejector can also be shortened to length if required.
Core pins
- Different core pin types available in different material variations
- E 1786 and E 1790 anti-twist core pins - without thickening on shank
- E 1742 core pins, non-nitrided for applications in die casting - easy machining thanks to hardness of 45 - 48 HRC
Copper core pins
Under thermal stress in the mould, the copper core pins provide rapid heat dissipation. This is particularly advantageous when cooling cores and inserts.
- Fast and targeted cooling of moulded parts thanks to maximum thermal conductivity
- Reduction of cycle time and best part quality due to optimal temperature distribution
- Highest strength due to beryllium-free copper alloy
