Our Services
- 1Sand Casting
Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.
Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.
- 2Investment Casting
Also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts and Titanium alloy by investment casting. It can achieve the best appearance with good tolerance
- 3Shell Casting
Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.
- 4Rapid Prototyping.
3D Printing and Rapid Prototyping service.
3D Scanning by physical sample.
- 5CNC Machining
CNC Milling, CNC Turning with 5 axis CNC center, we provide precision machining for all castings based on customers design drawings.
- 6CAD/CAM Design
Mechanical Design service based on customers requirement, our software is Solidworks and AutoCAD.

BS3146 Type CLA 1 Casting Chemical Requirements Composition:
| Grade | Carbon % | Silicon % | Manganese % | Nickel % | Chromium % | Molybdenum % | Copper % | Sulphur % | Phosphorus % |
| A | 0.15-0.25 | 0.2-0.6 | 0.4-1.0 | 0.4 | 0.3 | 0.1 | 0.3 | 0.035 | 0.035 |
| B | 0.25-0.35 | 0.2-0.6 | 0.4-1.0 | 0.4 | 0.3 | 0.1 | 0.3 | 0.035 | 0.035 |
| C | 0.35-0.45 | 0.2-0.6 | 0.4-1.0 | 0.4 | 0.3 | 0.1 | 0.3 | 0.035 | 0.035 |
Ni/Cr/Mo/Cu total amount shall not exceed 0.80%. www.castingquality.com
In our experience, the Ni/Cr/Mo/Cu is necessary to promote the tensile strength. when we compare those steel grade with EN10293 and ISO 3755, the tensile strength requirement is higher much than same yield strength steel grade.

Method: Invesment Casting, lost wax casting Material: Stainless steel SS304,SS316, CF8, CF8M Investment casting can get a good surface finish and dimension. So you only can machine little allowance to reach your requirement. If the mateiral change to steel, one cheaper investment casting can be adopted. Based on your drawings and detailed requirment, we will […]
Method: Investment Casting Material: Carbon Steel Casting, Stainless Steel Casting If necessary, we also supply ductile iron products by investment casting method. Pump fitting, include pump body, pump impeller and pump cover, are our mainly casting products. Some products are suitalbe for sand casting, you should compare the dimension tolerance and machining cost, to choice […]
