Ejector Pins During plastic injection molding and die casting operations, no other single mold or die component takes the beating ejector pins take. They’re always on the move. Always fighting friction. Thermal stress. Mechanical stress. And therefore, they’re always in danger of galling, seizing, bending or breaking if they’re not made of high quality steel with uniform strength - if they’re not hotforged properly - or if they’re not nitrided to exact specifications for case depth and hardness. Heads annealed for easy machining.

Frequently Asked Questions (FAQ) 1 How many shots do the Flexible Cores stand? As any mobile element, their lifetime depends essentially on their adjustment, as well as the tolerances used (which might be H7/g6). Flexible cores not being properly installed, may last a short period, but if they are installed as they should, they might produce more than 2 million pieces. Please, read our instructions for installation. 2 How is a Flexible Core correctly installed? Please, carefully read the instructions for installation. Furthermore, we want to stress that it is very important to correctly calculate the Flexible Cores length. If this is machined shorter than its emplacement, once the Flexible Core gets attached to the ejector plates, the central part gets elongated, bringing weakness.
CAD reference point
3 What would happen if the ejection stroke is more than C-dimension? When the Flexible Core head goes free out of its emplacement, due to the rounded shaft and screw attachment, this is prone to twist. This torsionnal movement affects to the thinnest zone which could, after several shots, break. A solution is to use our Keyed Flexible Cores, which have a flat on the shaft that prevents the rotation to occur. You could also make a flat on the rear zone of the Flexible Core shaft yourself, placing a cotter pin to hold it.

Flexible cores with mounting thread Simple Ejection
1 This area of support must be the same length as dimension H on the Sprung Core. 2 The adjustment area must be at least 1/3 of the dimension C. 3 The stroke of the sprung Core must be the same or smaller than the dimension C. 4 The plate that houses the shaft of the core must be minimum 15 mm in all cases. 5 The draft angle must be minimum 5째. 6 The core length must be 0,02-0,05 larger than its own hole. 7 After the core is adjusted, remove 0,1 to ensure smooth ejection.

Special applications require perhaps deviations from the listed standard components AW 275 and AW 280. Please fill your desired dimensions into the chart below. In order to maintain quality features (Service life tec.) the dependency of particular parameters in relation to eachother have to be observed. Agreement between customer and supplier in regard to dimensions or requirements (by example spring travel in relation to spring length) form the basis of well-performing parts.

Coatings PVD Coating Service Your coating plan for greater economy DME standard coatings LAM-A = chromium nitride (CrN) LAM-B = titanium nitride (TiN) LAM-C = titanium carbon nitride (TiCN) LAM-D = titanium aluminium nitride (TiAlN) LAMCOAT® = modified WS2 coating Further coatings on request
Correctly coated - for long-term use Excessive wear on tools for sheet metal and plastics processing results in shorter service lives. This in turn means high maintenance costs and problems caused by frequent production downtime. By using a coating that is adapted to the specific problem the wear caused by corrosion, abrasion and adhesion can be significantly reduced. Benefits: clearly measurable extension in service life, reduction in lubricants, improved flow properties for plastics and thus an increase in cost-effectiveness. The PVD Coating Service business unit at DME Normalien GmbH has many years’ experience and the optimum technology for coating tool steels, HSS, carbides and other electrically conductive materials at temperatures of between 200 and 550 degrees Celsius. We can find the right coating for your needs, depending on the material to be processed, the processing method, the product geometry and the target outcome. The treatment prior to coating is also an extremely important element in the successful use of a tool. Not only does our company have a range of methods to choose from, we also have experts with many years’ experience to ensure you receive the optimum surface quality. Depending on the requirement, rough polishing, fine-finishing and technical polished finishes are carried out in our own workshop, in order to achieve the optimum result in combination with the coating.
Your benefit: coatings which work economically LAM-A coating The CrN coating features excellent bonding strength and outstanding chemical resistance. Its high elasticity means that it can also be used on thin-walled workpieces, even those that are partially elastic. Plastics processing: for curved and functional surfaces where wear and corrosion problems occur as a result of chemically aggressive and abrasive fillers. Numerous benefits in terms of cost-effectiveness and durability of tools: • High wear resistance, particularly with glass-fibre- or mineral-reinforced plastics • Reduction in mould-release forces, fewer or no parting agents required • Increased corrosion resistance to acids and enclosed hot gases • Reduced wear in the feed orifice area • Lower edge wear • Improved cavity-filling process • Shorter cooling time • Reduced cleaning and repair costs • Increased productivity LAM-B coating Golden yellow colour, suitable for cutting and forming tools and some applications with plastics moulding tools, particularly in the processing of soft plastics, silicon and rubber. LAM-C coating A PVD carbide coating in which two reactive gases (nitrogen and a carbonaceous gas) are made to react with titanium. The carbonaceous gas makes the TiCN coating harder with a lower coefficient of friction at the same time. Mainly suitable for processing extremely ductile and hard materials for machining and stamping, for highly-stressed forming tools, clipping punches, die plates, bending tools and extrusion punches. LAM-D coating The particular features of TiAlN coatings are their good oxidation resistance and excellent hardness. The main areas of application are in machining, particularly for hard, ductile materials. The best results are achieved with HSC tools and dry processing. TiAlN is also suitable for special requirements in the fields of forming and stamping.

Definitions Brinell Hardness
Brinell hardness can be defined as the amount of force applied by a hard object, such as a steel ball, divided by the area of the indentation that the ball makes in the material. The output is read as a pressure (N/mm2, Kgf/m2, PSI).
Rockwell Hardness
The Rockwell hardness test is based on the differential in the depth of indentation produced on a sample’s surface by a primary (“minor”) and secondary (“major”) load and a specific sized indentor or “penetrator.” The difference in penetration depth between the two loads provides the measure of the hardness. The output would be read as a distance (mm, inch). There are several Rockwell scales for different ranges of hardness. The B scale (HRB) is used for soft metals and utilizes a steel ball as the penetrator, while the C scale (HRC) is used for hard metals and utilizes a cone-shaped diamond as the penetrator. Rockwell hardness numbers are not proportional to Brinell hardness readings.
Vickers Hardness
The Vickers hardness test method differs from the Rockwell (HRC) test method by using a square-based diamond pyramid penetrator, and the hardness number is equal to the load divided by the product of the lengths of the diagonals of the square impression. Vickers hardness is the most accurate test method for very hard materials and can be used on thin sheets of material. The output would not be a pressure value since the load is not divided by the area of the indentation.
Tensile Strength
Tensile strength can be defined as the quantity of stress required to overcome a material’s resistance to structural failure. Tensile strength is read as a stress or pressure value (N/mm2, Kgf/m2, PSI).
Kilogram-force
The deprecated unit kilogram-force (kgf, often just kg) or kilopond (kp) is defined as the force exerted by one kilogram of mass in standard Earth gravity. Although the gravitational pull of the Earth varies as a function of position on earth, it is here defined as exactly 9.80665 m/s². So one kilogram-force is by definition equal to 9.80665 newtons.[1] The kilogram-force has never been a part of the International System of Units (SI), which was introduced in 1960. The SI unit of force is the newton.
