Industrial Parts On Demand

CNC Machining

High-speed, automated cutting can be precisely formed into different shapes, and it is a computer-automated manufacturing process that uses pre-programmed software and codes to control the movement of production equipment for low-volume CNC machining.

Advantages of CNC

Dimensional Accuracy: ±0.003 inches.

Fast processing: reliable operation 7/24 hours.

Achievable mechanical properties: all desirable mechanical properties of the selected metal or plastic are preserved

sheet metal parts

Sheet Metal Manufacturing

Sheet metal fabrication is a subtractive manufacturing process, the process of converting flat sheets of steel or aluminum into metal structures or products by cutting, stamping, folding and assembling. Upload your CAD files to receive instant online steel fabrication quotes for custom formed sheet metal prototypes and production parts. Can be used for low-volume manufacturing and prototyping of metal parts.

Advantages of Sheet Metal Fabrication

Good mechanical properties, excellent formability, lower cost than some other steel alloys.

Injection Molding

Injection Molding

Plastic injection molding can turn thermoplastic materials into specific plastic parts, whether for high-volume or small-batch production.

Advantages of Injection Molding

Mold tolerance: ±0.05mm

Productivity: 1-100,000

Fast Delivery: Promise 10-15 working days for delivery

3D printing

3D Printing

3D printing is a manufacturing process in which three-dimensional parts or objects are created from digital 3D or CAD models. Suitable for low-volume manufacturing services. Confirm your CAD design, product function, dimensional tolerance, etc., to get a satisfactory finished product.

Advantages of 3D printing

Fast turnaround: Fast, efficient, and low-cost 3D printing and injection molding processes have replaced time-consuming and expensive manufacturing techniques.

Precise and diverse configurations: 3D printing can easily produce complex shapes, many of which cannot be produced by any other manufacturing method.

Product customization: increasing design freedom


Vacuum casting

Vacuum Casting

Vacuum casting is a custom manufacturing method used to produce small batches of functional plastic parts, where material is vacuumed into silicone molds to produce complex production parts.

Moderate vacuum degree, high cavity compactness and high casting quality.

Vacuum casting combined with computer mold flow analysis and simulation can predict the occurrence of casting defects, and can greatly save time and improve production efficiency for the design of modeling schemes.

aluminum extrusion
aluminum extrusion

Extrusions can be almost any shape and can be solid or a part with one or more hollow sections. We support various extrusion methods, such as aluminum extrusion and zinc extrusion, etc. to meet your specific requirements for low-volume manufacturing or high-volume production.

Advantages of Extrusion

Low part cost: Extruded frames and enclosures eliminate multi-part assemblies. High yields are also easily achievable and economical.

Reduced Tooling Costs: The simplicity of the extrusion process enables tooling costs to be 80-90% lower than other processes such as injection molding or die casting.

Part Complexity: Good for creating parts with complex cross-sectional shapes, including features such as undercuts, T-slots, and grooves.



Die Casting
Die Casting

Die casting is the manufacturing process of choice when producing large quantities of relatively complex metal parts and is widely used due to its versatility, reliability and accuracy. Meet your specific requirements for low-volume manufacturing or high-volume production.

Advantages of Die Casting

Complex Geometries: Efficiently produce custom die-cast parts with thin walls and complex geometries that are durable and dimensionally stable.

Strength: Stronger and more resistant to high temperatures than plastic injection molded parts.

Dimensional Accuracy: ±0.003 inches, but depending on your specifications, part geometry and materials, tolerances as small as ±0.001 inches are possible.

Custom Finishes: Metal finishing can produce castings with smooth or textured surfaces, painted and plated finishes. Finishes prevent corrosion and improve appearance.

General FAQs

If you need to keep producing the same set of parts on a monthly or quarterly basis, then you can opt for a manufacturing contract.

If you're still in the prototyping phase, we recommend using our platform for instant pricing and DfM feedback.

Hemtom has no minimum order requirements. Our services can help you scale from one-off products and prototypes all the way to mid-volume and high-volume production. Unit prices may drop significantly as volumes increase.

For manufacturing contracts, we select experienced engineers to produce all batches. Therefore, you can expect consistent part quality throughout the contract period.

Local tolerances are +.005”/-.005” for most metal geometries and +/- 0.010” for plastics. All manufactured parts have 0.010” dimensional and 1° angular tolerances.

Please standardize your needs in the inquiry, we can make adjustments for you according to our business level.
