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

The number provided by the customer and the part sample provided by the customer are providedCustom color matching.
Mold texturing Apply industry standard textures to molds, and you can expect to get the same effect as mold technology.
Threaded insert It can be achieved through secondary heat melting and ultrasonic welding processes.
Pad printing Transfer a two-dimensional image (such as a company logo) to a three-dimensional object.
Laser engravingApply to molds or directly to final parts to obtain information such as part numbers.
Basic assemblyThis includes fastening the molded parts we manufacture together and/or attaching labels to individually packaged parts.

The first line: Design the parts 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
Since we use an 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.
