Main Material Selection

General Casting serves a wide range of industries and applications, requiring flexible material selection to meet diverse requirements such as strength, corrosion resistance, machinability, and cost control. Materials with high versatility, cost-effectiveness, and ease of casting are typically preferred for general casting projects.

Common Materials for General Casting

Stainless Steel Series:
304/304L: Ideal for general corrosion-resistant components like brackets, housings, and flanges.
316/316L: Suitable for highly corrosive environments, including chemical, marine, and food processing industries.
410/17-4PH: Used for structural components or tools requiring moderate strength and corrosion resistance.

Carbon Steel Series:
1035/1045: Widely used for mechanical structural components and connectors.
1060/1065: Applied in parts requiring high hardness and corrosion resistance, such as gears and guide rails.

Alloy Steel Series:
42CrMo/4140: High-strength structural components and heavy-duty mechanical parts.
8630: Nickel-molybdenum alloy steel, suitable for case-hardened gears and shafts.

Other Alloy Series:
11L14/12L14 (free-cutting steel): For high-precision, general-purpose components.
A356 Aluminum Alloy: Lightweight, complex structural parts like housings and covers.

Key Casting Service Options

General Casting covers a variety of applications, including mechanical parts, hardware tools, and instrument components. The selection of casting methods emphasizes cost-effectiveness and adaptability.

Sand Casting:
Suitable for most common general casting needs.
Ideal for large-volume, simple-shaped parts, such as mechanical brackets and standard gearbox housings.
Offers low costs, mature technology, and meets basic structural requirements.

Investment Casting:
Serves niche and precision requirements in general casting.
Perfect for small connectors in precision instruments or corrosion-resistant parts for medical devices.
Provides high dimensional accuracy (tolerances of ยฑ0.05mm) and superior surface quality.
Can reduce expensive machining processes and control costs effectively.

CNC Machining:
Acts as a complementary method for general casting components.
Allows local dimensional adjustments, such as tapping and milling, to ensure compatibility with other parts.
Particularly suitable for small-volume, multi-specification, and customized general casting parts.

FAQ

We are a factory with over 20 years of experience in casting and machining. We have rich expertise in this industry. If you come across suppliers claiming to produce castings in a wide range of materials (such as steel, iron, stainless steel, copper, etc.), they are likely trading companies. If you see workshops actively producing parts, you can be assured that we are a genuine manufacturer.

Yes, as long as we receive CAD files or compatible 3D models that can be viewed with software like First Quote or Firstcut browser, we can provide a quotation. Please note that 2D drawings alone are insufficient for manufacturing precision components.

We support 3D CAD models from SolidWorks (.sldprt), ProE (.prt), and other CAD systems, commonly in IGES (.igs), STEP (.stp), ACIS (.sat), or Parasolid (.sat) formats.

We have an internal service system that responds to emails within 4 hours. If your request is urgent, please specify it in your email so we can prioritize your inquiry.

For rapid prototyping:
Silica sol casting: 20โ€“30 days
Sand casting: 7โ€“10 days
For mass production with machining included, the typical lead time is 45โ€“60 days.
More complex parts may require a different delivery schedule.

Yes, we provide samples based on your drawings for you to confirm structure and quality. If the sample does not meet your requirements, we will replace it free of charge until it is qualified.

We accept T/T (bank transfer), Alipay, credit card, etc. Typically, we require a 30% down payment upon order confirmation and the remaining 70% before shipment. For custom parts with complex requirements, additional pricing terms may apply.

We have a comprehensive quality control system that covers every step, from raw material procurement to machining processes and final inspection. For critical components, we strictly follow drawing standards and customer specifications.

All customer data is kept confidential. Only trained engineers are authorized to handle production orders. Third-party inspection or factory audits are welcome, or you may use our in-house quality team for final inspection.

Yes, we guarantee that all materials used are 100% genuine and as specified.

We value long-term cooperation and support our customersโ€™ production needs.

We believe every honest customer is a friend, and we treat our partnerships sincerelyโ€”building friendships and strong teams regardless of where our customers come from.
