Anti-noise
The contact surfaces of the manhole cover and its frame are meticulously machined to ensure a perfect fit, eliminating any abnormal noise. This precision engineering guarantees a quiet and serene environment, free from unexpected disturbances.

Anti-slip
The surface of the manhole frame boasts diamond-shaped block patterns, ingeniously cast to enhance grip. Its structural design involves interconnected rings, adorned with T-shaped protrusions that significantly boost the friction coefficient. This clever innovation ensures superior friction between the asphalt surface and the ring opening on auxiliary roads, providing unmatched stability and safety.

Anti-displacement
Firmly secured with anchor bolts (identified by the small round holes), the manhole frame remains steadfast during construction, unaffected by the road roller's pressure. This robust setup prevents any misalignment, thereby enabling standard and flawless construction results.

Anti-falling
Our advanced five-prevention manhole cover is equipped with an internal anti-falling grid. This innovative feature is designed to avert accidents by preventing people or objects from falling through, even if the cover is absent, thus ensuring public safety at all times.

Anti-theft
Beneath the manhole cover and frame lies an ingenious anti-theft hidden box and opening folding plate, a modern replacement for the traditional anti-theft chain. This effective solution not only deters theft but also eradicates rust issues caused by cavitation and water erosion, ensuring long-lasting durability.

FAQ

1. Casting process optimization category
Q: How to solve the problem of cracking in thin-walled die-casting products?
A: Suggest controlling the proportion of recycled materials to ≤ 30%, calculating the mold retention time based on a wall thickness of 1mm/3s, controlling the ejection delay within 0.5-2 seconds, and optimizing the mold cooling system.

2. Equipment and operation category
Q: How to handle emergency situations when the injection head is stuck in the goose neck area?
A: After the equipment cools down, try rotating the hammer head. If it cannot be rotated, replace the driver cylinder; Long term solution: It is recommended to upgrade the material of the material pot and regularly clean impurities.

3. Q: Is there intermittent discharge during material feeding?
A: Check if the nozzle is blocked (the gray section indicates blockage), which can increase the nozzle temperature by 5-10 ºC, shorten the nozzle departure time by 0.1-0.2 seconds, and moderately reduce the flow rate of the fixed mold cooling water.

4. Materials and Surface Treatment
Q: Does the casting have pattern defects after anodizing?
A: Adjust the uniformity of injection oil spraying and optimize the high-speed injection switching position; Regularly check the copper ion concentration in the oxidation tank (recommended ≤ 20ppm)
5. Mold maintenance category
Q: What should I do if the mold frequently sticks to the material?
A: Comprehensive solution: Reduce pouring temperature by 20-30 ºC Use polymer release agent Polish the surface of the mold cavity (use with caution for nitriding molds) Optimize sprue design to reduce metal liquid flushing
