Precision Die Casting Solutions Built for Performance and Scale
At Harbor Labs, we specialize in the design, production, and supply of precision die cast metal parts that meet the toughest performance standards. From concept to tooling, production to finishing, our die casting solutions are engineered to reduce lead times, eliminate quality variance, and optimize cost per unit — without compromise. Whether you require lightweight structural components or aesthetically-finished housings, we work across a global supply chain to deliver ISO:9001 certified die cast parts in aluminum, magnesium, zinc, and other non-ferrous alloys — tailored for sectors like automotive, lighting, construction, and industrial equipment.
What Is Die Casting?
Die casting is an efficient and highly accurate process used to create complex metal parts through high-pressure injection of molten metal into reusable steel molds — or “dies.” It enables tight tolerances, high production rates, and excellent repeatability, making it ideal for applications that demand both structural strength and fine detail.
Depending on the metal and part geometry, Harbor Labs offers both:
- Hot-Chamber Die Casting: For low-melting-point alloys like zinc
- Cold-Chamber Die Casting: For high-melting-point alloys like aluminum and brass
Post-injection, parts are cooled rapidly to form high-integrity components that are either ready for assembly or require minimal finishing.
