Specifications

Die-28D-B is a Complete pressing die with I.D. 1.1" (28.00 mm), which is used to to make sample pellets with diameter of 27- 28 mm SPECIFICATIONS: Model Number Die-28D-B Maximum Load 30 metric Ton (at room temperature) 960 MPa Material HRC 60 - 62 hardened steel Ra 0.08μm highly polished steel All pressing dies are made by high-stretched carbon steel to achieve high hardness to meet the essential requirements of making ceramic or metal samples. Otherwise, the pressing surface could probably get scratched. Material Requirement 32-75 Microns Do not use this die set for pressing powder with a particle size of 30 microns or smaller ; Small particles may slip into the gap of the die parts and damages the sleeve during the compression. Ball mill or ground the powder to the size of 32~75 microns powder before pressing . Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to separate the 32~75 microns particles from the powder clumps. For pressing sticky metal powders such as Al, Mg, Zn, it is necessary to use dry or alcohol-based tool lubricant to lubricate the die and sleeve set to reduce friction during the compression. Package Content One pressing die sleeve One top pressing die One bottom pressing die One support plate One die kit container Safety Precaution To avoid the risk of accidents and damage to the Pressing Die, please read these instructions carefully before installation and before using it for the first time. Read the manual, especially the die installation schematic, before the operation. Do not press flammable, explosive materials. The operator must wear a protection goggle. You must have a hydraulic pellet press equipped with the Protection Cover, please click the pictures to the left to order. To avoid damaging the die core and sleeve , we strongly recommend pressing powder with a professional laboratory hydraulic press to ensure the evenest pressing interface and uniform pressure force. Pressing Die Installation Schematic / Instruction Mixing and grinding chemical powder by agate mortar or Ball Mill Calcine mixed the powder in a high temp furnace under suitable temperature Crushing and Grinding calcined powder again by mortar or ball mill Put calcined powder into the die Pressing sample by a pressing machine under suitable pressure ( You may use CIP to press again to increase density about 5 - 10%.) Take out pellet sample from die Sintering the pellet under suitable temperature Application Notes Use ethanol to clean the pressing die before and after use every time Use anti-rust oil after the operation and store it in a dry place to avoid rusting. You may consider using BNMR for easy mold release. Please click the picture to order.
