Die Casting Parts We Manufactured
Types of Die Casting Processes at Termite Precision
To support a wide range of project needs, Termite Precision provides three types of die casting services, suited for different materials and deisgn complexities. We primarily apply hot and cold chamber casting. For components with tight tolerances and strong structural requirements, we offer advanced processes like semi-solid casting.
Cold chamber die casting melts metal in a separate furnace before casting. The molten metal is poured into a cold chamber, where a piston pushes it into the die under high pressure. The process handles high melting point metals like aluminum. The separation prevents contamination and extends die life. This type of die casting produces car engine parts, aircraft components, and electronic housings where strength and precision matter
Hot chamber, or gooseneck casting, connects the melting furnace directly to the casting machine. A piston pulls molten metal from the furnace and injects it straight into the die. This creates faster cycle times and reduces waste since the metal stays hot throughout the process. The process suits low melting point metals like zinc, magnesium alloys. The direct connection allows efficient high-volume production of toys, hardware, decorative items, and small mechanical parts.
Semi-solid die casting uses metal in a paste-like state between liquid and solid. The metal is heated to this semi-solid condition, then slowly pushed into the mold with less turbulence than liquid metal. This process reduces porosity and creates stronger parts with better surface finish. Semi-solid casting applies to aluminum and magnesium alloys effectively. The controlled flow produces automotive parts, aerospace components, and applications that need high strength and quality.

Qualitätssicherung
At Termite Precision, quality drives every step—from the tools we use to the standards we uphold. Our ISO 9001, ISO 14001, and IATF 16949 certifications guarantee consistent excellence.
Advanced Inspection Equipment
We use professional testing equipment for precise measurement and verification. Spectrometers analyze metal composition, coordinate measuring machines inspect complex 3D shapes, 2.5D instruments verify detailed features, and height gauges handle basic dimensions.
Comprehensive Testing Procedures
Parts go through four main tests: material analysis, durability testing, corrosion testing, and functional testing. These check your parts meet composition specs, handle tough conditions, resist environmental damage, and seal properly when needed.
Proven Quality Standards
Over 90% of parts pass first article inspection. And if there’s ever a quality issue, we’ll remake it for free. Every part gets checked before it leaves our facility.

FAQs
How much does a die casting project cost?
There is no “one-size-fits-all” price in die casting because costs depend on four key drivers: tooling (the mold), material volume, part complexity, and production quantity.
Production Volume: The higher your volume, the lower the per-part cost, as tooling expenses are amortized over more units.
Complexity: Features like undercuts, tight tolerances, or thin walls add to design and tooling complexity.
Tip: To get a precise quote, upload your CAD files today. Our engineers will perform a free DFM (Design for Manufacturing) analysis to help you identify cost-saving design optimizations before you spend a dime on tooling.
Why Choose Die Casting for Your Project?
High-Speed Production: Perfect for scaling from hundreds to thousands of parts.
Superior Surface Finish: Get smooth, retail-ready parts straight from the mold.
Tight Tolerances: Consistency guaranteed up to ±0.01mm.
Complex Geometries: Achieve intricate designs in a single production step.

What should I consider when designing for die casting?
When designing parts for die casting, several key considerations must be addressed to ensure optimal performance and manufacturability:
- Wall Thickness: Maintain uniform wall thickness to promote even cooling and solidification, reducing risks of defects like warping or internal stresses. Thin walls are preferred for faster cooling and material savings, but their feasibility depends on the metal used and part complexity.
- Draft Angles: Include draft angles in the design to facilitate the easy removal of the casting from the die. Typically, a minimum draft angle of 1 to 2 degrees is necessary, depending on the depth of the part.
- Fillet and Radii: Incorporate fillets and radii to eliminate sharp corners and edges, which can cause stress concentrations and crack initiation points. This adjustment also enhances the flow of molten metal within the die.
- Gating System: Design an efficient gating system to ensure proper flow of the molten metal into the die, minimizing turbulence and air entrapment. The placement of gates influences material distribution and part quality.
- Venting: Proper venting must be planned to allow air and gases to escape from the mold cavity during metal injection. This helps prevent porosity and incomplete filling.
- Simplifying Geometry: Simplify the geometry as much as possible to avoid undercuts and complex features that require intricate die mechanisms, which can increase tooling costs and complicate the casting process.
Can you post-machine die cast parts?
Yes, post-machining of die cast parts is not only possible but often necessary to achieve the desired precision and surface finishes that die casting alone might not provide. Post-machining allows for the attainment of tighter tolerances and smoother surfaces, which are crucial for high-performance and aesthetic requirements. Common post-machining processes include drilling, milling, and CNC machining, which refine the features of the die cast part to exact specifications.
Additionally, post-machining can correct any minor defects that occur during the casting process, such as porosity or surface imperfections. It also enables the addition of complex features and fine details that cannot be achieved through casting alone. By integrating die casting with post-machining, manufacturers can leverage the speed and cost-efficiency of die casting for the rough shape, while achieving the precision of CNC machining for critical dimensions and finishes.
What is the die casting process?
The die casting process is a high-pressure manufacturing method where molten non-ferrous metal is injected into a precision-engineered steel mold (die). At RapidDirect, we follow a rigorous 5-step process to ensure every part meets your exact specifications:
Preparation & Clamping: We start by lubricating the die cavities to ensure easy part ejection and temperature control. The two halves of the mold are then securely clamped under high pressure.
Injection: Molten metal (aluminum, zinc, or magnesium) is forced into the die at high speed and pressure (typically between 1,500 and 25,000 psi). This ensures the metal fills even the most intricate geometries.
Cooling & Solidification: The metal quickly solidifies inside the mold. Our advanced cooling systems ensure uniform temperature distribution to minimize internal stresses and warping.
Ejection: Once cooled, the die opens, and the “shot” (the part plus the excess material like gates and runners) is ejected via hydraulic pins.
Trimming & Finishing: The excess material is trimmed away. Depending on your needs, we then perform secondary CNC machining or surface finishing (such as powder coating or anodizing) to complete the part.
