Prolean’s Die Casting Service
Aluminum Die Casting
Aluminum die casting enables high-volume production with excellent dimensional stability and without the formation of microcracks.
Zinc Die Casting
Zinc die casting offers high precision, excellent surface quality, and strong, durable parts at a competitive cost.
What is Die Casting?
Die casting is a forming process in which molten metal or metal alloys are injected into a permanent steel mold (die) at high pressures, typically ranging from 150 to 1200 bar, and at high injection speeds that can reach 40 to 100 m/s. The mold is made of high-strength steel and is designed according to the specific requirements of each part. After solidification, the part is released from the die, and the process is repeated to achieve large-scale production of consistent, high-quality components.
We have many years of experience in the die-casting field and have served dozens of business and individual clients.

Finishing Options For Die Casting Products
At Prolean, we understand that the right surface finish is essential to the performance and appearance of a machined part. Every project has its own requirements, and we offer a complete range of surface-treatment solutions to meet them. With dozens of finishing capabilities—from protective coatings to aesthetic enhancements—our team ensures that each component not only functions well but also meets your desired visual and durability standards. Explore our available finishing options to find the solution that best fits your application.
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Electro-less Nickel Plating
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.
Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Nickel plating
Make the parts super resistive to corrosion. It enhances mechanical strength, hardness, wear resistance, lubricity, and ductility. Nickel plating is applicable in different materials, including Steel, aluminum, copper, and brass.
Passivation
Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
Yellow Chromate conversion coating
A shiny appearance with goldish color provides excellent corrosion resistance. It is applied on the surface of aluminum, magnesium, and their alloys. A layer of chromate also enhances the conductivity of parts
PTFE (Teflon) Coating
The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Die Cating Applications
Automotive
Die casting is widely used in the automotive industry for producing lightweight, durable parts such as engine housings, transmission cases, and structural brackets.
Industrial & Machinery
Die casting is ideal for producing durable, high-precision components used in industrial automation equipment. Typical parts include cylindrical housings, connectors, couplings, brackets, and actuator components, providing excellent dimensional stability and strength for long-term operational reliability.
Motors & Power Systems
Die casting is commonly used to manufacture robust motor housings, end covers, and heat-dissipation components. These parts offer excellent dimensional stability, strength, and thermal performance, making them ideal for electric motors, servo systems, and power-drive assemblies.
Lighting & LED Housings
Die casting is widely used in lighting applications to produce robust and thermally efficient housings. Aluminum die-cast heat-sink shells provide excellent heat dissipation, structural strength, and long-term durability, making them ideal for LED lamps, outdoor lighting fixtures, and high-power illumination systems.
Aerospace (Non-Critical Components)
Die casting is used in the aerospace industry to produce lightweight, durable non-critical components such as housings, brackets, covers, and structural supports. These parts offer excellent strength-to-weight performance and dimensional stability, making them suitable for auxiliary systems and interior assemblies.
