Precision Casting Wax For Automotive Parts, 1

$1 - $1 / Ton (US) (FOB)
MOQ: Not Specified
 
Precision casting wax is widely used in the manufacture of metal parts that require high precision and complex structures, typical areas include:
Aerospace: high-temperature alloy parts such as turbine blades and engine components.
Medical devices: casting of surgical instruments, orthopedic implants (such as titanium alloy joints).
Jewelry: production of fine patterned precious metal (gold, silver) jewelry.
Automotive industry: precision gears, sensor components, exhaust system parts.
Industrial machinery: pumps and valves, hydraulic parts, rapid prototyping of complex molds.
Art casting: sculpture, handicrafts and other metal artwork with high detail requirements.

Advantages of Precision Casting Wax
High dimensional stability: very low shrinkage under temperature and humidity changes, maintains the precise shape of the mold and is suitable for manufacturing complex, high-precision parts.
Excellent fluidity: after melting, it can fully fill the details of the mold and replicate fine patterns (e.g. turbine blades, jewelry patterns, etc.).
Low ash residue: minimal ash residue after burning or dewaxing to avoid casting surface defects.
Easy mold release: low adhesion to shell materials (e.g. ceramic shells), quick and complete melting out of the wax during dewaxing, reducing the risk of shell breakage.
Reusability: Waste wax can be recycled and reused, reducing costs.
Environmental protection and safety: Modern investment casting waxes are mostly formulated with non-toxic, low volatility synthetic waxes or natural waxes, which are in line with environmental standards.

Cr3-Cr5 Forged Rolls

$3.00K
MOQ: Not Specified
 
Roll produced by forging steel ingot. Forging can forge the metallurgical defects such as porosity and shrinkage cavity in the ingot, break the coarse casting structure, and obtain high-quality rolls with dense structure and uniform composition. Forged steel rolls have better strength and toughness, surface hardness uniformity and fatigue resistance than similar cast rolls. (Table 1) in order to meet the specific requirements of different rolling mills and rolling conditions, different alloy elements can be added to the roll steel to improve the roll performance. A certain amount of carbon and alloy elements have the following different effects on the structure and properties of forged steel rolls: carbon can increase the hardness and strength of rolls, reduce plasticity and improve wear resistance; Manganese can increase hardenability and strength; Silicon deoxidizes and improves strength; Chromium can increase hardenability, strength and wear resistance; Molybdenum can increase hardenability, strength and thermal hardness; Vanadium can control the grain size of steel and increase the strength. See Table 2 for the main chemical composition of common forged steel hot rolls and backup rolls.
