Injection Molding

One-stop Service from Low-volume to Mass Production

What Is Injection Molding?

Injection molding(also called plastic injection molding) is a manufacturing process start from 1940s. The advantages of injection molding are fast production speed, high efficiency, automatic operation, various designs, shapes from simple to complex, sizes from large to small, and accurate product dimensions. Widely used in daily necessities, consumer electronics, automotive industry, and aerospace, etc.

At BOYI Prototypes, we provide injection molding service from tools making to mass production including finishing service. We can produce 20 to 10,000,00+ parts in all kinds of plastic material.

Advantages of BOYI Injection Molding

Efficient for Mass Production

The tools can make high-volume production of parts into the millions.

Many 0ptional Plastic Materials

There are thousands of plastic material for injection molding.

Low cost

Large-volume and efficient production can ensure a low cost for every parts.

Outstanding Surface Quality

Usually, injection molded parts come out with very smooth surface.

The Injection Molding Process

After receiving the customer’s design and product drawing, we will make a DFM analysis report to discuss with the customer;

With confirming, we start to order the mold material-order the mold embryo-order the hot runner-print out the injection mold drawing;

The customer prepays 50% of the mold payment, and receives After the payment is received, the mold is first processed by programming a machining program, removing copper, and producing CNC and EMD processing drawings) and then processing.

The general process of injection molding processing is as follows:

1. EMD processing, testing the processed front and rear mold cores; injection mold electrode detection, testing tools: precision calipers, check the parameters of the injection mold one by one according to the requirements of the drawing

2. Wire cutting processing; slant top hole, flat top pinhole with slow wire processing

3. Carved bone position; some injection molds use precise engraving (the CNC machine requires extremely high precision) to process for a long time. The advantage is that there is no need to save the mold after carving, and the EMD processing time is also saved.

4. Milling machine processing;

5. Lathe processing

6. Mold clamping. The oblique top, the mating surface of the row position and the mold core, and the impact/insertion surface of the front and rear molds require FIT molds. This process takes time and effort, but is also an important part of mold quality;

7. Complete mold assembly-test mold. Also known as T1 T2

8. The product parameters of the surveying and mapping department are checked with the 2D drawings provided by the customer, and the samples are delivered to the customer without errors.

9. Customer feedback paid the final payment of the injection mold, and the mold was formally delivered to the injection molding workshop, ready for mass production.

Sheet Metal Fabrication

Sheet Metal Fabrication Prototyping and Large-volume Production

What Is Sheet Metal Fabrication?

Sheet metal fabrication is one of the traditional manufacturing process. Usually the material is steel or aluminum. In the process, the material will be turned into metal structures or products, by cutting, punching, folding and assembling. Sheet metal can be bent, cut or stretched into a variety of shapes, which is usually made by cutting and burning the metal material.

At BOYI Prototypes, we can supply cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum sheet (6061, 6063,etc.), aluminum profiles, stainless steel (mirror surface, brushed surface, matte surface). We can give professional advice according to product usage and cost.

Advantages of BOYI Sheet Metal Fabrication

High Production Efficiency

BOYI Prototypes use laser beam machining to improve the efficiency.

0ptional Materials

Brass, Aluminum, Stainless steel , and Zinc etc.

Customized Thickness

The thickness of sheet metal can be done as per client’s request.

Sheet Metal Fabrication Feeding Way

1. Shearing machine: It is a simple piece of material that is cut by a shearing machine. It is mainly prepared for die blanking. The cost is low and the accuracy is less than 0.2MM. Block material. Carbon steel laser cutting

2. Punching machine: It uses a punching machine to punch flat parts after unfolding the parts on the sheet in one or more steps to form various shapes of materials. Its advantages are short man-hours, high efficiency, high precision, low cost, and suitable for large batches. Production, but design the mold.

3. CNC: First of all, write the CNC machining program, and use the programming software to compile the developed drawing into a program recognizable by the CNC digital drawing machine, and let it punches out the various shapes of the flat plate one by one according to these programs But its structure is affected by the tool structure, the cost is low, and the accuracy is 0.15MM

4. Laser cutting is the use of a laser cutting method to cut out the structural shape of the flat plate on the large flat plate. The same as NC cutting, it is necessary to write a laser program. It can cut various complex-shaped flat pieces with high cost and accuracy At 0.1MM

5. Saw machine: mainly use aluminum, square tube, figure tube, round bar, etc., with low cost and low accuracy.

Pressure Die Casting

From 1 Prototyping to 1000+ Mass Production, Worldwide Delivery

What Is Pressure Die Casting?

Pressure die casting is quick, reliable and cost-effective for the metal manufacturing process. It’s similar to injection molding during works that by forcing molten metal under high pressure into a mold cavity.

With these characters, die casting wildly used for high-volume production of net-shaped
metal components that have tight tolerances.

At BOYI Prototypes, we can offer Aluminum Casting, Zinc Casting, and Brass Casting, etc.
Most die castings are made from above non-ferrous metals material, as well as Titanium and stainless steel.
