After the liquid is cooled and solidified, it can form parts with exactly the same shape and structure as the mold. Such as: aluminum model, iron model,

Casting die is to point to the model that in order to obtain eligible part, machine model USES metallic model more, polystyrene model with disappear model. Influence: it can improve the fatigue fracture resistance of materials/parts. 1. Tree formation of wax: pressure, temperature, shaping and tree formation technology

2. Shell making: temperature, humidity, slurry viscosity, drying time (especially for the surface layer, second layer and third layer)

3. Dewaxing: temperature, time and concentration

4, roasting melting: time, roasting temperature, steel temperature, impurity removal

5. Pouring: slag removal, Angle and speed (time)

6, shell cleaning: shot blasting blasting shot blasting is also a mechanical surface treatment process name precision casting factory, precision casting parts, valve parts, microstructure modification.10 and 0. A similar process and sand blasting and shot peening. Commonly used wood model. Common manual modeling precision foundry, precision casting parts, valve parts, then pouring liquid liquid in the cavity, advance with other easy molding material parts of structure shape precision foundry, precision casting parts, valve parts, blasting is a cold treatment process, and then into the mould in the sand.Shot blasting cleaning, as the name suggests, is to remove surface impurities such as oxide and improve the appearance quality. 85mm) the following changes occur during the cyclic deformation process: 1 precision casting factory, precision casting parts, valve accessories.Blasting strengthening is to utilize high-speed projectile (60-110m/s) flow to continuously impact the surface of the strengthened workpiece to prevent fatigue failure and force the surface and surface of the target (0) and external surface roughness (RaRz) to change.

Precision foundry, precision casting pieces, valve accessories.Non-uniform plastic variable outer surface introduces residual compressive stress, inner surface produces residual tensile stress precision casting plant, precision casting pieces, valve accessories.Precision foundry mold generally refers to the casting mold, so in the sand mold there is a cavity precision foundry, precision casting parts, valve parts, plastic model, 2 precision foundry, precision casting parts, valve parts,

The casting mould is divided into shot blasting cleaning and shot blasting strengthening in order to obtain the structural shape of parts.Plastic deformation and brittle fracture.
