1: PROJECT INITIATION & FEASIBILITY REVIEW
We begin with a deep collaborative analysis of your part design, material selection, and performance requirements. Our team conducts a formal Design for Manufacturability (DFM) assessment, identifying potential challenges and optimizing the design for cost, quality, and cycle time before any tooling commitment.
2: CONCEPT DESIGN & FLOW SIMULATION
Our engineers develop the initial mold architecture, determining parting lines, gate locations, and ejection strategy. We then perform advanced mold flow simulation (CAE) to virtually analyze fill patterns, temperature gradients, and potential defects. This digital prototyping phase validates and optimizes the design for optimal performance.

The 8-Stage Mold Design & Delivery Process: Engineered for Certainty
3: DETAILED ENGINEERING & DESIGN FREEZE
Every component is modeled in full 3D detail. We finalize all critical systems: cooling channel layout, venting design, slider & lifter mechanisms, and the ejector system. A comprehensive Tooling Design FMEA (Failure Mode and Effects Analysis) is conducted. The finalized design package is submitted for your formal approval.
4: PRECISION MANUFACTURING & IN-PROCESS QC
With your signed approval, manufacturing commences. Master toolmakers utilize high-speed CNC machining, precision EDM, and deep-hole drilling to fabricate each mold component from premium steel. In-process inspections via CMM and hardness testing ensure every piece meets exacting specifications before assembly.
5: MOLD ASSEMBLY & MECHANICAL VALIDATION
All components are meticulously assembled by senior mold technicians. The complete tool undergoes dry-cycle testing and mechanical function checks to verify smooth operation of all movements—clamping, ejection, and actuation of side-cores—ensuring flawless mechanical performance.
6: SAMPLE TRIALS (T1) & PROCESS OPTIMIZATION
The mold is installed in a die casting machine for the first-shot trial (T1). We produce initial samples while meticulously documenting and optimizing key process parameters (injection speed, pressure, temperature). The goal is to establish a stable, repeatable process window.
7: SAMPLE VALIDATION & DESIGN VERIFICATION
Trial samples undergo rigorous analysis. We perform comprehensive First Article Inspection (FAI), dimensional CMM reporting, and X-ray inspection for porosity. Data is compared against your CAD model and specifications. Any required minor adjustments are implemented in this phase.
8: FINAL APPROVAL, DOCUMENTATION & DELIVERY
Upon your approval of the validated samples, the project concludes. We deliver a complete mold data package, including final inspection reports, maintenance manuals, and process setup sheets. The mold is then prepared for secure shipment or released for scheduled production at your designated facility.
HOT CHAMBER DIE CASTING VS. COLD CHAMBER DIE CASTING
WHAT IS DIE CASTING?
For the die casting process, your metal material is melted and then transferring into a mold or a steel die. These molds or steel die allow us to mold the metal into the shape of the part you need for your project. Once the mold is filled it has a brief cooling off period to allow the metal to harden.

Take a deeper dive into the mechanisms of die casting below.
DIE CASTING MOLD DESIGN
We start by partnering with you to refine the part design for manufacturability, performance, and cost-efficiency, using DFM and flow simulation to prevent issues before tooling. The mold is typically composed of two or more halves, facilitating the filling and removal process during casting.
Step 1
MELTING & PREPARATION
High-grade metal (magnesiu & aluminum) alloys are melted in controlled furnaces. The molten metal is then degassed and refined to remove impurities, ensuring material purity and strength.
Step 2
HIGH-PRESSURE INJECTION
The prepared metal alloys are injected into the mold cavity under intense pressure (800-1200 bar). This forces the metal to fill intricate details rapidly, capturing complex geometries with precision.
Step 3
RAPID, UNIFORM COOLING
Our temperature-controlled molds manage heat extraction to minimize internal stresses and shrinkage, yielding parts with excellent mechanical properties and dimensional stability.
Step 4
EJECTION & TRIMMING
Once solid, the mold opens, and the new casting is ejected automatically. The part is then trimmed to remove excess material (sprues and runners) and prepared for finishing.
Step 5
FINISHING & QUALITY ASSURANCE
The casting undergoes secondary processes like CNC machining, deburring, and surface treatments (e.g., powder coating, anodizing). Each part is rigorously inspected for dimensional accuracy, structural integrity, and cosmetic finish before delivery.

COLD CHAMBER HIGH PRESSURE DIE CASTING CAPABILITY
There are two primary methods for die casting: hot chamber die casting and cold chamber die casting. For aluminum alloy die casting, we primarily employ cold chamber pressure die casting machines, while the hot chamber method is often used for alloys like zinc due to their lower melting points.
At Bian Diecast, our factory is fully equipped with a variety of die casting machines. Each machine is capable of producing at least 2000 to 3000 die casting components per day. The largest casting area reach 3125cm².

WHY IS THE MOLD SO CRITICAL?
Determines Part Quality: The mold's precision directly defines the part's dimensional accuracy, surface finish, and structural integrity.
Impacts Production Efficiency: A well-designed mold with efficient cooling allows for faster cycle times and higher productivity
Affects Long-Term Cost: While the initial mold is a significant investment, a durable, well-made mold can last for hundreds of thousands of cycles, making it cost-effective for high-volume production.
Enables Complexity: It allows for the production of intricate shapes, thin walls, and integrated features (like bosses and ribs) that would be difficult or impossible with other manufacturing methods.
| Aspect | Hot Chamber Die Casting | Cold Chamber Die Casting |
| Typical Alloys | Lower Melting Point Metals: • Zinc (Zn) • Magnesium (Mg) • Lead (Pb) • Tin (Sn) |
Higher Melting Point Metals: • Aluminum (Al) • Copper (Cu)/Brass • Some Magnesium (Mg) alloys |
|
Process Schematic |
The gooseneck (injection cylinder) is permanently immersed in a pool of molten metal housed within the machine | The injection chamber (shot sleeve) is separate from the melting furnace. Molten metal is ladled manually or automatically into the cold chamber |
| Cycle Speed | Very Fast (can be <1 second for small parts). No metal transfer step | Slower, Ladling step adds time. Higher pressures may require longer intensification |
| Advantages | • Faster cycles, higher production rates • Better process stability & consistency • Reduced metal oxidation & contamination • Longer gooseneck life |
• Can cast high-melting-point alloys (Al, Cu) • Produces higher-integrity, denser parts • Handles larger part sizes • More versatile for alloy choice |
| Disadvantages | • Limited to lower melting point alloys • Generally smaller part sizes |
• Slower cycle times • Higher risk of porosity if not optimized • Higher wear on shot sleeve and plunger |
