Kritika Die Mould Accessories Co is the Replaceable Blade Ejector Pins Manufacturers in Pune. We employ specially selected tool steels like HSS, H13, SKD61 and DIN 1.2344 to manufacture our Blade Ejector Pins depending on if the pin has to be used in high-heat, high-wear or corrosive moulding operations. The flat section of the pin, which is narrow and also more prone to stress, is specially through-hardened so as to help it hold its shape without becoming too brittle. We typically harden our pins to around 48–52 HRC but modify the hardness range to suit the moulding cycle requirement of the customer. All our pins are tempered and straightened following the hardening process and are subsequently precision-ground to maintain even thickness across the length of blade. Extreme care is taken in terms of tolerance on the sharp edge and additional care is taken to chamfer or polish the blade end such that the latter cuts clean without causing tears and scratches on delicate part surfaces.
We can get you the most Steady Blade Ejector Pins in India. All our manufactured Blade Ejector Pins undergo multiple stages of grinding, flatness checking and polishing to the correct level of parallelism between the blade faces. This is essential for high-performance tools, as mis-alignment of a stroke and flatness of edges result in moulding surface irregularities on the moulded article. We produce the blade and shank of the Blade Ejector Pin as a single-piece build to deliver maximum strength and dependability. This single-piece monolithic build reduces breakages, especially when fitted to long-stroke moulds and high-speed moulds. To add extra protection against wear and tear, reduce friction, and increase the life of the ejector system, we also coat our Blade Ejector Pins using advanced coatings. These are Titanium Nitride (TiN), Titanium Carbo-Nitride (TiCN), and DLC (Diamond-Like Carbon), as per whether moulding is with an abrasive moulding compound, a fiberglass-reinforced moulding, or a moulding with a high thermal cycling moulding. The coatings mentioned above give a maximum surface hardness of up to 80 HRC to permit longer life to the pins with minimal risk of galling, scuffing, or seizure.
