PqMold offers customizable surface finishes that elevate your product’s appearance, resistance, and quality beyond expectations. Our finishes cover tool marks and enhance hardness, roughness, and corrosion resistance. Explore our options for flawless results.
Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.

The hot chamber zinc die casting process is a manufacturing technology that uses molten zinc to make high-precision metal parts. This process’s workflow typically involves the following steps:
Explore key information about zinc die casting processes, alloy selection, tooling design, surface finishing, and production efficiency. This section answers common questions about tolerances, durability, and how PQMold delivers high-quality zinc die cast components with consistent performance and cost control.
Zinc strength, ductility, and stability enable specialists to create a more durable product. This high ductility makes zinc perfect for die casting processes that require pressure and expansion to be maintained without fracturing.
Die-cast zinc is cheaper to produce than stainless steel. Stainless steel is more expensive to produce than zinc. Zinc alloys are more resistant than stainless steel and are used for thin-walled profiles. Stainless steel is far inferior to zinc alloy in terms of thin-walled sections.
Zinc casting alloys are strong, long-lasting, and low-cost engineering materials. No other alloy system combines strength, toughness, rigidity, bearing performance, and cost-effective castability.
The combination of low melting point, excellent fluidity, dimensional accuracy, surface finish, strength, corrosion resistance, and recyclability makes zinc a favorable material for die casting. These properties contribute to the production of high-quality, precise, and cost-effective parts in various industries.
The melting temperature is one of the most visible variances. Zinc melts at a lower temperature than aluminum, magnesium, and brass, at 723°F. As a result, zinc requires less energy to reach a molten state than other die cast metals.
When exposed to moisture and other environmental conditions, zinc corrodes. However, the corrosion that occurs does not cause the part to rust in a brown and orange color or considerably weaken it. As a result, zinc die casting is both economical and robust, and it may be employed in a range of industries
The required usual minimum wall thickness in zinc die castings is 0.040″ (compared to 0.060″ in aluminium die casting). However, thanks to today’s better die casting and alloy technology, die casting components with wall thicknesses as low as 0.008″ have been produced.
