Pattern Allowances in Casting are very important if it is neglected during the casting process. Then the parts we produce may be smaller than the required size. This can result in huge financial losses. So choosing suitable allowances in casting pattern can greatly improve efficiency and avoid waste. So how to use Pattern Allowances in […]

Casting production is a complex multi-step process. The level of skill in each process varies greatly. The skills of the operator, quality management, and equipment all affect the final quality of the casting. If you want to know what are the various types of casting defects? What are the causes of casting defects, and how […]

The basic function of riser and gating system is a fundamental difference. The role of the gating system is to make the liquid metal fills the cavity, and at the same time, remove the slag. Feeding, the role of the riser is mainly in order to prevent the shrinkage cavity formation of castings, which provide […]

The size of the investment casting are high precision and low surface roughness, so most of the surface can not machining or less processing, machining allowance can not or less left. However the machining allowance for how much still depends on the casting processing method, and the size of the processed surface, and the casting […]

Molding wax injection locations poorly designed, thick wall parts not feeding. Casting wall thickness difference is too big, thick, thin in cooling rate. Mold material overheating, molding temperature is too high, cause a large mold material shrinkage rate, solidification time growth. Injection pressure and holding time is not enough, did not get full filling and […]
