Zinc Die Casting Processes
We offer a variety of technologies for zinc die casting, including but not limited to:
✔️ Multi-Slide Die Casting
Featuring 5-15 average cycles per minute (CPM), up to 6 slides for complex geometries, hydraulic thrusters delivering up to 6 tons of locking force (A2 thruster & A206SIS only), flexible crosshead adaptor systems, and fast pneumatic injection systems.
✔️ Hot Chamber Die Casting
Our automated multi-slide and conventional machines—featuring internal melting pots, aluminum hot chamber capability, and up to 6 slides for complex geometries—are ideal for low melting-point alloys.
✔️ Sub Assembly
Subassemblies join small metal components via insert moulding, overmolding, and similar techniques.
✔️ Overmolding
Overmolding materials enable complex, high-quality products across consumer, industrial, military, and medical sectors—enhancing grip, sealing, vibration/noise damping, impact resistance, and visual appeal while reducing labor, part count, and errors.
✔️ Insert Molding
Insert moulding involves placing metal components into a mould prior to injecting molten metal around them to form a finished part.
Zinc Die Castings Design Capabilities
| Design Elements | Specific Value/Range | |||
| Uniform Wall Thickness | Aim for wall thickness between 1.5mm to 4mm for optimal casting flow and to reduce material wastage. | |||
| Draft Angles | Use a 1° to 3° draft angle on vertical surfaces to ease part removal and prevent damage to the mold. | |||
| Radii and Fillets | Incorporate 2mm to 4mm radii at corners and edges to improve flow and reduce stress concentrations. | |||
| Avoid Sharp Corners | Sharp corners can cause stress and are difficult to cast. Use a minimum 2mm radius to improve moldability. | |||
| Incorporate Ribs and Bosses | Design ribs with a thickness of 0.5mm to 1mm and maintain proper spacing (2-3 times the thickness) for strength without adding excessive material. | |||
| Correct Gate Placement | Gates should be placed at the thickest sections, and the gate thickness should be about 1mm to 2mm to ensure even metal flow and avoid cold shuts. | |||
| Optimized Thickness for Strength | For balance, wall thickness should be between 1.5mm to 4mm, ensuring a lightweight and durable part. | |||
| Proper Tooling Design | Vents should be spaced about 30mm to 50mm apart, with runners about 5mm to 7mm wide to ensure proper air evacuation and metal flow. | |||
| Consider Post-Processing Needs | Allow for 0.1mm to 0.3mm tolerance for any CNC machining or secondary finishing, such as polishing or painting. | |||
| Avoid Deep Blind Holes | Avoid blind holes deeper than 2-3 times their diameter. If needed, use through holes to simplify casting. | |||
| Minimize Undercuts | Minimize undercuts in the design to reduce complexity in tooling. Consider using side-action tooling or simplifying the design. | |||
