With our experience in metal parts and we consult our clients to choose the most cost effective process under different points of view:

- Required quality of metal products surface
- Required dimensional accuracy of metal products
- Quantity of metal products
- Influeuce on the design of metal products with selected process.
- Metal products material
- Type of pattern and core box equipment needed
- Cost of making the mold(s)

Each casting process has its advantages
depended on the products needs

: Sand Casting

Sand casting is one of the most popular and simplest types of casting, and has been used for centuries. Sand casting allows for smaller batches than permanent mold casting and at a very reasonable cost.

: Shell Mold Casting

Our foundry in Qingdao does shell mold casting for steel and aluminum. The resin sand mold enables complex geometries to be cast. We typically manufacture medium size parts require high accuracy such as gear housings, heat exchanger, connecting rods, and lever arms.

: Die Casting

The die casting process forces molten metal under high pressure into mold cavities (which are machined into dies). Most die castings are made from nonferrous metals, specifically zinc, copper, and aluminum-based alloys, but ferrous metal die castings are possible. The die casting method is especially suited for applications where many small to medium-sized parts are needed with good detail, a fine surface quality and dimensional consistency.

: Forging

Forging is divided into hot forging and cold forging.The hot forging manufacturing process is performed at extreme high temperature (up to 1150 °C for steel, 360 to 520 °C for al-alloys, 700 to 800 °C for cu-alloys). The cold forging manufacturing process is performed at room temperature. The work piece is squeezed between two dies until it has assumed their shape. the technique includes rolling, drawing, pressing, spinning, extruding and heading.

: Stamping

JOYO has strong capabilities in Normal stamping (Blanking, Bending, Forming, Piercing, Coining…),Progressive die and high-speed stamping.From low to high quantity items we are your preferred manufacturer for stamping products. We provide all secondary finishing processes such as welding, bending and surface treatment like powder coating and anodizing.
