Core and ejector pins

Ejectors are highly stressed parts in the mould. Depending on the plastic part to be demoulded, certain types of ejector pins are required for example for different service lives or mould temperatures. There is a wide selection of different materials, geometries and coatings available. Why are we your perfect choice? It’s easy − we have the right ejector for every application.

Overview

Are you familiar with our comprehensive range of ejector pins? 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.

Ejectors with DLC coating

Increased corrosion resistance and service life
Guaranteed interchangeability through exact tolerances
Excellent dry-running properties enable use in cleanrooms
Minimised wear thanks to excellent sliding properties
Leave no stains on plastic parts

To the complete range

Ejectors from HSS

Suitable for high mould temperatures thanks to best high-temperature resistance
High durability through low wear and high hardness (~ 64 HRC)
Increased service life when used with plastics with a high glass fibre content

Ejector pin, through-hardened, HSS E 17103 Ejector pin offset, through-hardened, HSS E 17003

Ejector pin stainless steel

Especially for use in cleanrooms
Optimally suited for processing aggressive plastics

Ejector pin, stainless steel, through-hardened E 17109

Ejectors with anti-twist lock

Ejector pins with precise anti-twist lock for exact positioning
Anti-twist lock already provided on the head enabling cost-effective production of contour ejectors
Two different anti-twist locks with different dimensions available from stock

Ejector pin offset, through-hardened, with anti-twist lock E 1702 Ejector pin through-hardened, with one-sided anti-twist lock E 1711 Ejector pin through-hardened, with anti-twist lock E 1712

Ejector sleeves

Hardened ejector sleeves from 1.2210
Nitrided ejector sleeves from 1.2343

Ejector sleeve, through-hardened E 1720 Ejector sleeve, nitrided E 1750

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

To the blade ejector range

Ejector pin for ventilation

Fast, targeted ventilation of the cavity via the ejector pin
Can be cut to length thanks to ventilation surfaces along almost the entire shaft length
Optimal guidance of the ejector due to g6 tolerance on the shank

Thanks to the ventilation surfaces along almost the entire shaft, fast and targeted ventilation of the cavity via the ejector pin is possible. The ejector can also be shortened to length if required.

Core pins

Different core pin types available in different material variations
Core pin, non-nitrided E 1742 for applications in die casting – easy machining thanks to hardness of 45–48 HRC
Anti-twist core pins E 1786 and E 1790 – without thickening on shank

Core pin, non-nitrided E 1742 Contour core pin E 1786 Contour core pin from hot-work steel E 1790

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

Copper core pin E 1780
