Technology Advantages of Precision Casting


【Rapid】 Its fast speed and low cost allow it to take only 2-3 days to get the lost prototype mold, thus meeting the business needs of many varieties and small batch

【Superior】 The wax mold with complex spatial structure can be printed, and its dimensional accuracy is close to that of the mold-pressing wax mold

【Clean】 Only 0.05% ash residue is produced, with no heavy metal elements and no pollution of casting

【Exquisite】 The surface quality of the mold is excellent, and the details have strong performance. After processing, the surface roughness can reach Ra1.6, and the minimum print size can be only 0.3mm


When is SLA Rapid Precision Casting Needed?

☑ Process design optimization

☑ Tight delivery schedule

☑ A small quantity (within 50 pieces), when the mold production cost is high

☑ Special structure making the opening of the mold possible

☑ Test piece and prototype verification



Details Analysis of the Casting Process

I. Modeling

The shell extraction function of pre-processing software used to process the prototype mold into a hollow structure: to achieve significantly reduced consumption of resin raw materials, and cost savings; eliminate the expansion problem of resin in post-processing basically; greatly reduce the amount of ash left in the process.


Manufacturing of the prototype mold with 3D printing: No matter how complex the prototype mold is, it can quickly manufacture the mold. Free from mold opening procedures, it can achieve huge savings in time and cost.


Software required: UnionTech Polydevs pre-processing software

During data processing, the Polydevs pre-processing software allows users to customize the shell wall thickness, the length and width of the internal supporting arm, and freely choose the location to place the discharge hole. The lightweight process avoids shell expansion during dewaxing.

 

Equipment: UnionTech Lite600 SLA Printer

Materials: Somos photosensitive resin 111222, Element

It has a very low ash content. And the surface ash is very easy to be cleaned. Moreover, it has such characteristics as low viscosity, stable size, smooth surface of components, easy surface treatment, product stability, etc.
