1. What is the High Precision and High Airtightness Aluminum Die-casting Radiator production line?

It is an automatic production line by Longhua designed to produce high-precision, high-airtightness aluminum die-casting radiators. The line is user-friendly, optimized for quality and efficiency, and intended for high-demand manufacturing environments.

2. What is the production capacity?

The machinery is rated to produce up to 2000 radiators per day. The specification also lists a capacity of 1000 pieces per 8-hour shift, which aligns with multi-shift operation to reach the daily throughput.

3. What materials are used for the machine and the final product?

The final radiators are aluminum die-cast products. The production equipment is listed as made from stainless steel (machine components/body), providing durability and corrosion resistance.

4. What are the power and electrical requirements?

The standard voltage requirement is 380V (three-phase supply). For specific site power requirements or alternate voltage options, contact Longhua or your sales representative.

5. Is the production line fully automatic and easy to operate?

Yes — the line is described as automatic and user-friendly. Longhua provides controls and automation to reduce manual intervention; operator training is typically provided as part of commissioning.

6. What does 'high precision' mean for these die-cast radiators?

High precision refers to tight dimensional tolerances, consistent wall thickness, and improved surface finish achieved through accurate die-casting, tooling, and process control. This leads to better fit, performance, and reduced post-processing.

7. What does 'high airtightness' mean and why is it important?

High airtightness means the radiators have minimal porosity and leakage paths, improving fluid containment and heat-transfer performance. It reduces the need for rework and leak-failure risk in HVAC and automotive applications.

8. Can radiator dimensions and tooling be customized?

Yes. Dimensions are listed as customizable. Custom tooling/dies and layout adjustments can be provided to match your product specifications — lead time and cost depend on the complexity of the custom tooling.

9. Which industries and applications is this line suitable for?

Typical applications include manufacturing aluminum radiators for automotive cooling, HVAC systems, industrial heating solutions, and home heating applications.

10. What site preparation and footprint are required?

Dimensions are customizable so footprint depends on your configuration. Typical requirements include a leveled foundation, adequate power (380V three-phase), proper ventilation/exhaust, and access for installation. Longhua can supply a site layout and detailed requirements during planning.

11. What maintenance is required and are spare parts available?

Routine maintenance includes lubrication, inspection of moving parts, mold care, and periodic replacement of wear components. Longhua supplies spare parts and recommends a maintenance schedule; discuss spare parts packages with your sales contact.

12. How does Longhua ensure quality control and testing?

Quality control typically includes dimensional inspections, pressure/leak testing for airtightness, surface inspections, and process monitoring. Specific QC procedures can be tailored and discussed with Longhua during purchase.

13. What certifications or standards does the equipment meet?

Certifications are not listed in the basic specification. For CE, ISO, or other compliance and test reports, contact Longhua to obtain the available certification and documentation for the specific machine model.

14. Is installation, commissioning, and training included?

The product description notes the equipment is user-friendly, and manufacturers commonly provide installation and commissioning services plus operator training. Confirm the exact scope of on-site support and training with Longhua or your supplier.

15. How do I get pricing, lead time, and place an order?

Pricing and lead time depend on customization (tooling, layout, optional features). Contact Longhua or an authorized distributor with your product specifications and required capacity to receive a formal quote, delivery schedule, and ordering instructions.
