Manufacturing Capabilities
Engaged in the research, development, sales service of CNC Machining, 3D Printing and Vacuum Casting.
GH Prototype is a leading supplier providing CNC machining services to customers worldwide. We can fabricate components using a wide range of materials, including various engineering plastics, alloys, and other specialized materials. Equipped with high-speed, high-precision CNC machines, we ensure timely delivery of parts—often completing orders in as little as 3 to 5 days.
CNC machining is ideal for both plastic and metal parts, whether you’re working on a single prototype order or large-scale production runs of up to tens of millions of units.
We offer machining capabilities for an extensive array of materials, including low-carbon steel, stainless steel, aluminum, magnesium, zinc, brass, as well as a diverse selection of plastics—though the final choice ultimately depends entirely on the customer’s specific requirements.
Vacuum casting is a specialized technique that uses polyurethane resin to produce high-quality plastic or metal parts in small batches.
Casting is a manufacturing process in which liquid material is poured into a mold and allowed to solidify into the desired shape. In this method, parts are cast under vacuum conditions, ensuring that the final products are free of bubbles, rich in detail, and match the quality of injection-molded components—while also being faster and more cost-effective.
SLA and SLS are the two most common processes in 3D printing.
SLA 3D Printing: 3D CAD data is used to liquefy a material, which is then layered on top of each other and cured with ultraviolet light to achieve solidification and drying. Afterward, these models are cleaned and moved on to the final curing stage. Prototypes produced using SLA laser printing technology boast extremely high precision, allowing even small-scale prototypes to capture highly detailed, high-resolution features.
SLS 3D Printing: SLS laser rapid prototyping is a layer-by-layer process designed to create functional prototypes with full capabilities. In 3D SLS printing, a CAD design is divided into multiple digitally defined, evenly thick layers, which are then selectively fused together layer by layer using a laser.
Sheet metal fabrication is a process that involves shaping flat metal sheets—typically ranging in thickness from 0.15 mm to 10 mm—into various components and structures.
We provide customers with one-stop plastic component services, covering mold flow analysis, part design, mold design, mold manufacturing, injection molding, secondary processing, and parts distribution. Additionally, we can also offer complementary assembly services tailored to customer needs, as well as die-casting molds customized to meet specific client requirements.

In the product development phase, vacuum casting (also known as silicone molding) is an ideal choice. It allows us to quickly produce small-batch samples with intricate structures at a relatively low cost. These components exhibit mechanical properties that closely resemble those of the final product, significantly accelerating the design validation process.
