What is Custom Die Casting?

Custom die casting makes metal parts special. The mold shapes metal with high precision. It uses metal alloys like A380 and A360. Moulage sous pression machines can have 400-450 tons of clamping force.

The molten metal fills the mold fast. The mold cools, and the metal hardens. Ejector pins then push out the finished part. Parts have smooth surfaces and accurate dimensions. This process helps make car parts and gadgets. Custom die casting improves production quality.

How to Design Custom Die Casting Parts?

Tolerances

Custom Die Casting makes sure pieces fit right. Use a caliper to measure. It must be exact, like 0.01mm. Next, CNC machines cut parts very precise. The mold’s shape needs careful checking.

Any mistake can change the piece. Quality control tools test every part. They find tiny errors. Engineers adjust specs to fix problems. Micrometers help see tiny gaps.

Good tolerances keep pieces working well. Now, all parts fit like a puzzle. Careful work ensures success in making parts.

Complex Geometry

Shapes can be tricky. Engineers design molds with CAD software. Curves and angles need attention. Each line must match. CNC mills cut these shapes. Machines use G-code for commands. Next, check all the angles. They must be perfect.

3D printers make some test parts. Precision is important. Engineers use simulations to see if pieces fit. If not, they change the design. Good geometry means parts work well. Making complex shapes takes skill and care.

Surface Finish

Parts need to be smooth. Polish the custom aluminum die casting mold. Buffing wheels make it shiny. Then, check for tiny bumps. Sandpaper helps smooth rough spots. Next, apply a coating. This helps with release. Inspect for scratches. Fix any flaws.

The finish must be even. Glossy or matte, it needs to look right. Finally, check under a light. The surface should be perfect. Smooth parts are key for good products. Nice finishes make everything better.

Draft Angles

Draft angles help parts come out. Set the angle in CAD. The mold needs these angles. Next, CNC machines cut them. Angles must be just right. Check with a protractor. If the angle is off, fix it.

Draft angles stop parts from sticking. They help with release. Engineers test the mold. Good angles mean easy release. Fix any problems early. This makes the process smooth. Draft angles are important for good casting.

Ejector Pins

Ejector pins push parts out. Place them in the die casting mold. They need to be strong. Next, check the placement. They must not leave marks. Pins should move smoothly. Engineers test the pins. They push parts out gently. Adjust if needed. Ejector pins stop parts from getting stuck.

They help with quick release. Check pins often. Make sure they work well. Ejector pins make the custom die casting process faster and better.

Parting Line

Parting lines split molds. First, design the line in CAD. It must be exact. Next, CNC machines cut the mold. Check the line for accuracy. It should be smooth. Parting lines help in separating molds. Engineers inspect the line. Fix any gaps or overlaps. Good lines ensure clean parts.

If there’s a problem, adjust the mold. Parting lines make the process easier. Accurate lines are key for quality parts.

What are the Steps in the Custom Die Casting Process?

Mold Preparation

First, the mold must be clean. Next, the die cavity is lubricated. The mold gets preheated to about 200 degrees Celsius. It makes the mold ready for the molten metal. The mold halves are then clamped together tightly. Special clamps called toggle clamps are used.

These clamps ensure the mold doesn’t move. Then, a plunger injects the molten metal into the mold. It fills every part of the cavity. The plunger moves quickly, ensuring a smooth flow.

Metal Melting

The metal is heated in a furnace. This makes it turn into liquid. The furnace can reach 1,200 degrees Celsius. Special alloys like aluminum and zinc are used. These alloys melt evenly.

The liquid metal is then scooped out. This step uses a ladle. The ladle pours the metal into the die casting machine. It is essential to control the temperature. A thermocouple helps measure it accurately. This ensures the metal is just right.

Die Casting

Next, the molten metal is injected. This step is called custom die casting. It goes into the die under high pressure. The pressure can reach 20,000 psi.

This makes sure the metal fills every part. The die is kept closed during this process. Special pins called ejector pins help remove the part. The casting machine does this very quickly. It ensures the metal solidifies properly. The die opens up once the metal cools down.

Cooling Phase

The metal cools down inside the mold. This makes it solid again. Cooling channels in the die help this process. These channels carry coolant fluid. The fluid absorbs heat from the metal.

A chiller helps keep the fluid cool. The cooling phase can take a few seconds. It depends on the metal used. A timer controls the cooling time. This makes sure the metal is fully solid.

Trimming

Once cooled, the casting is removed. It has extra metal called flash. The flash needs trimming. A trim die is used for this. The casting is placed in the trim die. Then, it is pressed down.

This removes the flash. The casting now has a clean edge. This step is essential for accuracy. A trimming press helps speed up the process. It makes sure each piece looks perfect.

Finishing

The casting needs a final touch. This step is called finishing. It removes any rough spots. Special tools like grinders are used. These tools make the surface smooth. Sometimes, the casting is polished. This makes it shiny. Other times, it is painted. A coating helps protect it.

Each casting is checked carefully. Custom die casting quality control ensures no defects. This step makes sure the casting is ready to use.
