Low-pressure permanent mold (LPPM) casting uses a gas at low pressure, usually between 3 and 15 psi (20 to 100 kPa) to push the molten metal into the mold cavity. The pressure is applied to the top of the pool of liquid, which forces the molten metal up a refractory pouring tube and finally into the bottom of the mold.
The XGC88000 crawler crane, unlike the majority of crawler cranes, comes in two sections. The primary section consists of the crane itself, which boasts a maximum boom length of 144 meters, a maximum total length of 173 meters (including the counterweight radius), a maximum height (when fully erect) of 108 meters, a lifting capacity ranging between 3,600 and 4,000 tons [10] [11] [12] (although ...
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, and stamped to a specific shape in a 2-part mold. Or a vacuum can be used to pull the plastic sheet onto the mold in a simplified process known as vacuum forming. The excess material is trimmed off and recycled.
Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow.

It is built of strong rubber-coated fabric or a polymer film used to compress the part during cure or hardening. In some purposes, the bag encloses the entire material, or in other purposes, a mould is used to form one face of the laminate with the bag being a single layer to seal to the outer edge of the mould face.
