Pellet Pressing Die with Vacuum Port (Optional ID size 2 - 25mm) up to 400C - Die-Va

Va-Die is a customized pellet die with 1/4" vacuum (or gas) port for pressing samples from 2 mm to 25 mm ID. You may vacuum the die during pressing to make the sample dense or blow gas via the port to make the sample easy to take out.

Maximum Load	Please click the picture below to see the max. load for each size of the die Max. pressure less than 800 MPa is recommended. Please check the corresponding force with metric ton unit for your die size, and recalculate the maximum pressure (reading from pressure gauge) for the pellet press.
Installation schematic	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 Must read the manual, especially the die installation schematic, before the operation The operator must wear protective goggles Must have a Pellet Press equipped with the Protection Cover, please click pic-2 to order You may order a vacuum pump separately for the dies ( click picture below right)
Cautions	WARNING: DO NOT press flammable, corrosive, or explosive materials The operator must wear a protective goggle Attention: 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 NO pressing powder with particle size LESS THAN 30 microns should be used. Small particles may slip into the gap between the pushing rod and the steel sleeve and cause damage to the sleeve during the compression Ball mill or ground the powder to a size of 32~75 microns before pressing.  3'' Dia. Sieve Set No.200&450 Mesh can be used to separate the 32~75 micron particles from the powder clumps . Suggestions: Please use a professional laboratory hydraulic press to ensure the evenness of the pressing interface  For pressing sticky metal powders, such as Al, Mg, Zn, please use dry or alcohol-based lubricants to reduce friction during the compression.
Application Note	You may consider using BNMR for easy mold release. Please click the picture below to order.
Steps to make sample pellet	Mixing and grinding chemical powder by an agate mortar or a Ball Mill Calcine mixed the powder in a high-temperature furnace at a suitable temperature Crushing and grinding calcined powder again by gate mortar or Ball Mill Put the calcined powder into the die Pressing a sample by a pressing machine under suitable pressure Take out a pellet sample from the die Sintering the pellet under a suitable temperature in Oven Then, a new material sample is formed!
