Comprehensive Guide to Dongrun Casting Industry Co., Ltd.
Dongrun Casting Industry Co., Ltd. is a leading manufacturer specializing in cast aluminum and machining for over 30 years. With an extensive background in the casting industry, we are committed to delivering high-quality products and exceptional service to our clients worldwide. Below, we address some of the most frequently asked questions about our company, services, and processes to help you better understand our capabilities and operations.
1. Are You a Trading Company or Manufacturer?
Dongrun Casting Industry Co., Ltd. is a factory—not a trading company. We exclusively focus on cast aluminum and machining, leveraging over two decades of expertise in this niche field. Unlike trading companies that may offer casting services for various materials such as steel, iron, stainless steel, or copper, we dedicate ourselves solely to aluminum casting, ensuring superior quality and precision.
If you require casting services for other materials, we are happy to assist by recommending reliable partners free of charge. It is our pleasure to support your needs and guide you toward the right resources.
2. How Can I Obtain a Quotation From Your Factory?
To provide you with an accurate quote, we require a 3D CAD solid model of your design. This model serves as the foundation for preparing our First Quote interactive quote. Please note that two-dimensional (2D) drawings are insufficient for quoting or manufacturing purposes.
We accept the following file formats:
- Native SolidWorks (.sldprt) or ProE (.prt) files
- Solid 3D CAD models exported in IGES (.igs), STEP (.stp), ACIS (.sat), or Parasolid (.x_t or .x_b) formats
By supplying a high-quality 3D CAD model, you enable us to deliver precise pricing and production plans tailored to your requirements.
3. When Can I Expect to Receive a Price Quote?
Typically, we respond to inquiries within 48 hours. If your request is urgent, please contact us directly via phone or indicate the urgency in your email. This ensures your inquiry is prioritized, and we can expedite the quoting process for you.
4. What Is Your Lead Time for Production?
Our lead times vary depending on the type of casting process and the volume of your order. Below is a general breakdown:
Tooling & Samples
- Sand Casting:15–30 days after receiving advance payment
- Gravity Casting, Low Pressure Die Casting, High Pressure Die Casting:30–60 days after receiving advance payment
Mass Production
The delivery time for mass production depends on the complexity of the items and the quantity ordered. We will provide a detailed timeline once we review your project specifications.
5. Can You Manufacture Products Based on Samples?
Yes, we can produce parts based on your samples or technical drawings. If you provide samples without accompanying drawings, our team can create detailed drawings based on your samples to ensure accurate production.
6. What Is Your Sample Policy?
We offer one free sample (valued at under USD 15 per piece) once production is completed according to your drawings. However, customers are responsible for covering freight costs. If additional samples are required, they will incur a cost based on production expenses.
7. Can We Use Your Current Tooling or Request Samples Displayed on Your Website?
Unfortunately, we cannot accommodate such requests. Dongrun Casting Industry Co., Ltd. exclusively accepts OEM orders and manufactures casting parts based on client-provided drawings or samples. We do not sell existing designs or products to third parties.
To ensure confidentiality and protect intellectual property, we have signed Non-Disclosure Agreements (NDAs) with all our clients. Tooling and drawings belong solely to our clients, and we only use them for authorized production purposes. Clients may retrieve their tooling at any time upon settling tooling costs.
8. Do You Test All Goods Before Delivery?
