Anti-noise
The contact surfaces of the manhole cover and the manhole frame are expertly machined to ensure a perfect fit, effectively eliminating any chance of abnormal noise, thus offering a quieter and more serene urban environment.

Anti-slip
Ingeniously designed diamond-shaped block patterns adorn the surface of the manhole frame, enhancing both aesthetics and function. This frame utilizes an interconnected ring structure, complemented with T-shaped protrusions, significantly increasing the friction coefficient. This innovation ensures superior grip between the asphalt and the ring opening, thus providing a safer and more reliable surface after installation on auxiliary roads.

Anti-displacement
The manhole frame is securely anchored to the ground using high-strength anchor bolts, visible in the small round holes in the figure. This precision engineering prevents misalignment during construction, safeguarding against displacement caused by road roller operations and ensuring impeccable alignment standards are maintained.

Anti-falling
Introducing the revolutionary five-prevention manhole cover, featuring an innovative built-in anti-falling grid. This ingenious design prevents accidents by stopping people or objects from falling through in the unlikely event of a cover being misplaced, ensuring safety for all.

Anti-theft
Our state-of-the-art anti-theft solution includes a discreet hidden box and an opening folding plate beneath the manhole cover and frame, effectively replacing traditional anti-theft chains. This comprehensive system not only deters theft but also addresses rust issues caused by cavitation and water erosion, offering a long-lasting, secure, and rust-free solution.

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
