Design criteria: Cast molding
Our basic guidelines for magnesium alloy die casting include important design considerations to help increase the moldability of parts, improve appearance and reduce overall Production time.

Customized color matching is provided on the number provided by the customer and the part sample provided by the customer.
Mold texturing Applying industry standard textures to molds, you can expect the same effect as mold technology.
Threaded inserts can be achieved through secondary heat melting and ultrasonic welding processes.
Padding Transfer a two-dimensional image (such as a company logo) to a three-dimensional object.
Laser engraving is applied to molds or directly to final parts to obtain information such as part numbers.
Basic assembly includes fastening the molded parts we make together and/or attaching labels to individually packaged parts.

The first line: Design a part with thicker features, and the resulting sink after molding. Middle row: shows parts designed to have thicker features.
Bottom: Demonstrates how to remove thicker features to help create well-formed parts.
Radius
Because we use automatic CNC milling process to make part molds, the corners of some parts will have radii instead of sharp edges. This usually does not require changes to the model, but the resulting radius can be determined before milling the mold.
