What Is Vacuum Casting? (Quick Overview)

How the vacuum casting process works

Vacuum casting helps make strong plastic parts. First, you need a master model. You can make this model with 3D printing or CNC machining. The process uses silicone molds to copy the master model. Here is how vacuum casting works:

1. Make a master model with SLA, SLS 3D printing, or CNC machining.

2. Put the master model in a casting box. Pour platinum-cure RTV silicone over it.

3. Cut the silicone mold with a wave-line method. This lets you take out the model and put in resin.

4. Heat the casting resin to 40 °C. This helps the resin flow better.

5. Fill the mold with resin in a vacuum casting machine. The pressure is 5 mbar or less.

6. Cure the mold in an oven at 60 °C to 80 °C. This makes the parts strong.

7. Open the mold and take out the finished part.

Vacuum casting gives you parts that look and feel like real products.

Advantages of vacuum casting

Vacuum casting has many good points. Here are some main benefits:

• Cost-effectiveness: Vacuum casting saves money for small and medium batches.

• High-quality results: You get smooth surfaces and fine details.

• Material versatility: You can use many kinds of resins.

• Speed: You can make prototypes fast with vacuum casting.

• Customization and complexity: Vacuum casting works for special shapes and designs.

Cost Breakdown of Vacuum Casting in China

Understanding the cost structure helps you plan your vacuum casting project. You can see where your money goes and how to control your budget. Let’s look at the main price components you will find when you outsource vacuum casting in China.

Typical price components

You pay for several steps in the vacuum casting process. Each step adds value to your parts. Here are the main cost components:

Master model / 3D printing cost

You start with a high-quality master model. This model sets the shape and detail for every part you make. You can use 3D printing or CNC machining to create your high-quality master model. The price depends on the size and detail. A simple high-quality master model costs less. A complex high-quality master model with fine features costs more. You need a high-quality master model for each new design. The high-quality master model is the base for the silicone mold.

Silicone mold cost

The silicone mold is the heart of vacuum casting. You pour silicone around the high-quality master model to make the silicone mold. The silicone mold copies every detail from the high-quality master model. You need a new silicone mold for each design or major change. The cost of the silicone mold depends on the size, shape, and number of parts you want. A small silicone mold costs less. A large silicone mold for many parts costs more. The silicone mold can make 15 to 25 parts before you need a new one. You pay for each silicone mold you use. The silicone mold cost is a one-time fee for each batch.

Per-unit casting cost

After you have the silicone mold, you pay for each part you cast. The per-unit casting cost covers the resin, machine time, and labor. The silicone mold lets you make many parts from one high-quality master model. The more parts you make, the lower your average cost. If you order a small batch, the per-unit casting cost is higher. If you order more, the cost per part goes down. The silicone mold helps you save money on each part.

Painting, polishing, and finishing

You may want your parts to look smooth and colorful. Painting, polishing, and finishing add extra cost. You can ask for matte, glossy, or textured surfaces. The silicone mold gives a good base, but finishing makes your parts look even better. If you want special colors, you can add pigment to the resin before casting in the silicone mold. You can also paint the parts after casting. Polishing removes small marks from the silicone mold. Each finishing step adds to the total cost.

Assembly or additional processes

Some parts need assembly or extra steps. You may want to join several cast parts together. You may need inserts, threads, or special coatings. Each extra process adds cost. The silicone mold can include some features, but not all. You pay more for each added step. Ask your supplier what the silicone mold can do and what needs extra work.

Cost comparison: China vs USA vs Europe

You want to know how costs in China compare to other regions. China offers lower prices for vacuum casting. You pay less for the high-quality master model, silicone mold, and per-unit casting cost. Labor and material costs are lower in China. You also get fast service and flexible batch sizes.

You save money by choosing China for your vacuum casting project. The silicone mold and high-quality master model cost less. You get more value for your budget.

Factors that affect pricing

Many things can change the price of vacuum casting. You should know what affects your costs. Here is a table that shows the main factors:

Let’s look at some key details:

Complexity of geometry

If your part has many small details, you pay more. The high-quality master model takes longer to make. The silicone mold must copy every feature. Complex shapes need more work and skill. Simple shapes cost less.

Material selection

You can choose from many resins. Some resins cost more than others. If you want special properties, you pay more. The silicone mold works with many materials, but some need extra care.

How to Outsource Vacuum Casting in China (Step-by-Step Guide)

If you want to outsource vacuum casting in China, you should follow a simple process. This helps you avoid problems and get good results. You need to get your project details ready and learn about each step.

Step 1 — Prepare your RFQ

You must send a Request for Quotation (RFQ) to your supplier. This lets the factory know what you need. They can give you the right price.

3D files (STEP/IGS/X-T)

You should give 3D files like STEP, IGS, or X-T. These files show the part’s shape and size. Factories use them to make the master model.

2D drawings with tolerances

You can add 2D drawings with tolerances. These drawings show important sizes and limits. They help the supplier check if the parts are correct.

Material & color requirements

You need to tell the supplier what material and color you want. You can pick ABS-like, PC-like, or other polyurethane materials. You can also choose colors or ask for clear parts.

Quantity & lead time

You should say how many parts you need and when you want them. This helps the supplier plan when to make and send your order.

Tip: If your RFQ is clear, suppliers can give you faster and better quotes.

Step 2 — Mold creation & sample confirmation

The factory uses your 3D files to make a master model. They build a silicone mold around the model. The mold is heated to 60-70℃ to make it accurate. The supplier mixes the casting resin and removes air bubbles. They pour the resin into the mold using a vacuum. The part is baked in an oven before it comes out. Each step makes sure the part matches your design.

Step 3 — Trial production / T1 batch

The supplier makes a small batch called the T1 batch. You get the first samples. The factory checks these samples with special tools. You can look at the samples and see if they are good.

• Custom parts are checked for quality before you get them.

• You can ask for changes if you need them.

Step 4 — Mass production & QC

If you like the samples, the factory starts making more parts. They use tools like 3D CMM to check sizes, X-ray to look inside, and hardness tests. You get reports and can track each batch.

Step 5 — Packaging & shipping

The supplier packs your parts so they do not break. You can pick air or sea shipping. The factory gets customs papers ready for export. You get your finished vacuum-cast parts ready to use.
