Die Casting Capabilities Overview
Lewei Precision has a variety of die casting services that aim to serve different industries. Manufacturing quality production components, as well as the fast-prototyping process, our abilities will guarantee the high quality, long-lasting, and high-performance components, where each of them performs exactly according to your needs.
Hot chamber die casting is ideal in metals with low melting points like zinc and magnesium and therefore it has a high rate of cycles and wasted material is minimized hence is ideal in large production volumes.
It is applied to high-melting-point metals such as aluminum that offer the required strength and accuracy to components that must be able to endure stressful environments such as aerospace and automotive components.
Semi-solid die casting gives high strength and low porosity components with enhanced surface finish, which would be suitable in the automotive and aerospace industries, where part wear and performance are vital.
SLM applies laser to liquefy metal powders to create metal components with high strength. This method is perfect in aerospace, medical and industrial applications because it is long-lasting and precise to use under harsh conditions.
Available Die Casting Finishes
Lewei Precision has a range of die cast finishes to meet your parts needs; functional, aesthetic, and lasting requirements. To achieve a polished appearance, better corrosion resistance, or even better performance, we offer you the choices that suit your requirements.
The as-cast finish is a perfect choice where aesthetics are less important as it preserves the raw texture of the part and it is used when the part is an internal part or prototype.
A bead blasted finish produces a textured finish with a matte look, which enhances the life of the part, and gives it a consistent look, which is ideal in parts that are subject to wear and environmental elements.
Anodizing provides a protective coating of aluminum parts improving their corrosion resistance and wear. It is also customizable in terms of colors, thus it is an excellent product in terms of both protection and aesthetics.
In powder coating, we use a smooth coating which is long lasting and provides a lot of protection against chemicals, abrasion, and the elements. Perfect in components that require heavy and durable cover.
Wet painting enhances appearance of parts besides providing a protective layer. It is a perfect selection of functional and aesthetics components that have a variety of colors to fit your design requirements.
Plating is a coating of the surface to parts with a thin layer of metal to improve characteristics such as corrosion resistance, conductivity, and surface finish, so it is suitable in electronic parts or heavy-duty applications.

压铸的优缺点
Die cast components have a high strength-weight ratio which means that the total load is minimized without compromising on durability. This makes them suit the automotive and aerospace industries where weight and strength are critical.
The die-cast metals are ideal in harsh or outdoor environment applications because of the natural oxide that forms on them which helps them to resist rust and degradation.
Die-cast metals are recyclable with 100% and this will be helpful in fulfilling sustainability as it reduces waste and makes them environmental friendly.
Die- cast Parts are compatible with T-slot and can be quickly assembled with straightforward joining techniques which aids in saving on production time and costs.
Die casting is capable of producing compound outlines in one extrusion, and it provides design freedom that is best in components with complicated designs.
Lower machining costs compared to solid aluminum blocks, making it a more affordable option for high-volume production runs.
Initial cost of tooling and molds may be expensive. The price, however, is compensated by the efficiency and savings in large volume production runs..
Die-cast components may contain surface run-offs and may need a finish or polishing. This may introduce more time and expense particularly on parts whose surface is visible.
The die cast process can be influenced by design modifications and this may need new tooling to ensure quality; this will incur unnecessary additional cost and time..
Once tooling is made, shape modifications can be difficult. Significant design changes may require new tooling, which increases the overall cost.
Setup and trimming create scrap material, leading to some waste, though this can be minimized with optimized designs and processes.
Die casting press capacity limits the maximum part dimensions that can be produced. Larger parts may need additional processes or different methods.
