Silent Operation Mastery
Every element of the contact surfaces between the manhole cover and frame is meticulously machined to perfection, ensuring an impeccable fit that guarantees absolute silence, eliminating any potential for unwanted noise.

Enhanced Anti-slip Innovation
Ingeniously designed, the manhole frame showcases diamond-shaped block patterns that are crafted into its surface. This innovative frame exhibits an interconnecting ring structure. Additionally, T-shaped protrusions strategically enhance the friction coefficient on the ring opening's surface. This advanced design significantly augments the friction between the asphalt base material and the ring opening when laid on auxiliary roads, ensuring superior anti-slip performance.

Unyielding Anti-displacement Assurance
With robust anchor bolts securing the manhole frame firmly to the ground (observe the small round holes in the image for their dedicated fixing function), the framework remains immovable during construction. This steadfast anchoring prevents any misalignment of the manhole frame opening, even under the heavy rolling of road rollers, ensuring flawless construction standards.

Sophisticated Anti-falling Mechanism
The innovative five-prevention manhole cover is fortified with an internal anti-falling grid, ingeniously designed to shield against accidental falls. It provides a protective barrier, securing the safety of individuals and objects, should the manhole cover ever be misplaced.

Impenetrable Anti-theft Defense
Underneath the manhole cover and frame, an ingenious anti-theft hidden box and opening folding plate are seamlessly integrated, effectively replacing conventional anti-theft chains. This cutting-edge solution delivers a comprehensive anti-theft function, eradicating rust issues caused by cavitation and water exposure, and ensuring enduring protection.

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
