Product Feature And Application 

Core Process and Technology:

High-pressure die-casting: Through customized molds and high-pressure injection processes, the integrated molding of complex explosion-proof cavities and heat dissipation rib structures is realized, the welding gap is reduced, and the overall explosion-proof performance is improved.

CNC precision machining: The die-cast blank is milled for sealing surface, threaded hole finishing and explosion-proof joint surface grinding to ensure that the explosion-proof gap is ≤0.1mm.

Enhanced surface treatment: Nickel plating or electrostatic spraying can be selected to meet the anti-corrosion requirements of explosion-proof scenes.

Performance advantages:

Explosion-proof and safe: The die-cast shell is combined with precision processing of the flameproof surface to effectively block the spread of internal explosions.

Efficient heat dissipation: The die-cast honeycomb heat dissipation structure and internal air guide duct reduce the risk of temperature rise during long-term operation of the lamp.

Corrosion resistance and anti-aging: Aluminum alloy substrate + surface treatment process, resistant to acid, alkali, salt spray and UV aging, with a service life of more than 10 years.

Application scenarios

Petrochemical: Lighting equipment housing in explosion-proof areas of refineries and chemical plants.

Mine tunnels: Explosion-proof lamp housings for underground operations and areas where gas is easily gathered.

Offshore platforms: Anti-corrosion and explosion-proof lighting for offshore oil drilling platforms and port terminals.

Warehousing and logistics: Safety emergency lighting equipment for flammable gas warehouses and dusty environments.

FAQ 

Q1: Why choose die-casting instead of welding molding?

A1: The die-casting process can form complex cavities in one piece, avoid weld weaknesses and air leakage risks, and improve explosion-proof reliability.

Q2: How long is the processing cycle and mass production delivery time?

A2: The mold development cycle is about 15-25 days (depending on the complexity), the sample delivery is 10 days, and the mass production order is completed in 25-30 days.

Q3: Does it support non-standard sizes and special explosion-proof structures?

A3: Yes! Customizable special-shaped shells, multi-cavity explosion-proof designs, and provide thermal simulation and pressure burst testing services.

Q4: Does surface treatment affect explosion-proof performance?

A4: The surface process has been verified by explosion-proof certification to ensure that the accuracy and material performance of the explosion-proof surface are not changed, and it is safe and compliant.

Q5: What is the minimum order quantity (MOQ)?

A5: Die-casting customization MOQ starts from 200 pieces, supporting small batch trial production + later expansion to reduce customer inventory pressure.
