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.
Vacuum casting technology offers a wide variety of materials to facilitate the creation of cast urethane parts, typically for functional test, pre-production evaluation and low volume production. Cast auto urethane parts are quick and inexpensive without the need to invest any metal tooling when quantities are only dozens of short runs, and can be delivered within weeks in most instances.
Standard lead time Up to 10 copies within 15 working days
Standard accuracy ±0.3% (with lower limit on ±0.3 mm on dimensions smaller than 100 mm)
Minimum wall thickness To ensure that the mold is filled properly, a wall thickness of at least 0.75 mm is necessary. For best results, we recommend a wall thickness of at least 1.5 mm
Maximum part dimensions The size of the mold is limited by the dimensions of the vacuum chamber (1900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters)
Typical quantities Up to 25 copies per mold (depending on the mold's complexity and the casting materials)
Surface structure High-quality surface finish comparable to injection molding.
Advantages of Silicone Auto parts Vacuum Casting :
Great for low volumes
Self-coloured parts
Low upfront investment
Production like parts
Massive range of materials
Rubber like parts and over molds
Flexible parts are often referred to colloquially as â??rubberâ?? parts. Whilst rubber forms a substantial proportion of them, there are also flexible polyurethanes and thermoplastic elastomers to consider.
Advantages Of Auto Oil And Gas Rubber Parts Vacuum Casting
â?¢ Low cost for molds
â?¢ Molds can be made in a few days
â?¢ Many types of polyurethane resins are available for casting, including overmolding
â?¢ Cast copies are highly accurate with excellent surface texture
â?¢ Molds are durable for 20 or more copies
â?¢ Perfect for engineering models, samples, rapid prototypes, bridge to production

Prototyping flexible parts
The advantage of prototyping parts designed from rubber or flexible elastomers such as silicone, is that it enables you to confirm the required rigidity of the material before committing to production tooling. However, prototyping flexible parts can be a challenge!
The quickest option is to 3D print â??rubberâ?? or other flexible parts, however whilst they may demonstrate a level of elongation in a variety of harnessesâ??, their properties fall well short of production intent materials and little can be done to improve the layered surface finish. (Note, flexibility can be achieved through additive techniques but tear strength, chemical resistance and elongation to break will be significantly reduced).
So Shbury will select vacuum casting to produce auto oil and gas rubber parts to increase the tea strength.
The original model for vacuum casting is generally created using the stereolithography method. From this model, a primary mold of silicone is created and filled in the vacuum chamber with liquid polyurethane casting resin (PUR). The vacuum prevents bubbles and shrink holes even in complex molded parts. After hardening, the service of the casting is finished. Given the numerous available polyurethanes and ureols (PU hard foam), many conventional production plastics (injection molding) can be simulated.
Whether rubber-soft, last, semi-rigid or ABS rigid, there are vacuum casting resins for a very wide range of material requirements and priorities. Two component parts (hard/soft) or inserts are also possible. The dimensional precision of molded parts in vacuum casting is �± 0.1 mm or 0.2%. In vacuum casting, the maximum yield from one silicone mold is approximately 20 molded parts. There are no demolding chamfers and added material to compensate for shrinkage in vacuum casting.
