I. Technical Background and Industry Position

Hebei Junchi Sports Equipment Co., Ltd. is located in Haixing County, Cangzhou City, Hebei Province. Relying on the location advantages of the Jinsan Expressway and the coast of the Bohai Sea, the company has been deeply engaged in the sports equipment industry for nearly 10 years. With an integrated model of "R&D + Production + Service," the company focuses on the research and manufacturing of products such as curling tracks and outdoor fitness equipment. Its curling track technology, with high-precision manufacturing processes and stable performance, is widely used in domestic professional venues and training bases, and has become one of the industry's technical benchmarks.

Chapter II: Core Technology Analysis: Curling Lanes Manufacturing Process

1. Material Selection and Proportion
The curling track surface is made of high-density polyethylene (HDPE) material, with a thickness of 8-10mm, featuring a wear resistance coefficient ≥0.3 and impact strength ≥50kJ/m². This ensures the track maintains a surface flatness error ≤0.5mm even in low-temperature conditions (-18℃ to -5℃). The underlying support structure is a steel frame, paired with a moisture-proof and heat-insulating layer, effectively resisting the effects of ground moisture and temperature fluctuations on the track.

2. Manufacturing Process and Precision Control
The manufacturing process is divided into three steps: mold forming, surface treatment, and assembly.
- Molding: Special molds are processed through CNC machine tools to ensure the track curvature conforms to the World Curling Federation (WCF) standards (radius of curvature 15.24m).
-Surface Treatment: Track ice patterns are created using laser engraving technology, with a depth of 0.2-0.3mm and uniform spacing with an error ≤0.1mm, simulating the friction force of a real ice surface.
- Assembly: Modular design for quick installation, single track segment weight less than 120kg, joint gap ≤ 0.3mm, secured with high-tensile bolts to ensure overall stability.

3. Environmental adaptability optimization
For the cold climate in the north, the track is internally equipped with temperature sensors and heating wires, which can monitor and adjust the surface temperature in real time, preventing changes in friction due to frost formation. At the same time, drainage channels are designed at the edges to prevent melting snow and water from permeating and affecting the track structure.

3. Technical Parameters and Compatible Scenarios

Hebei Junchi Curling Track technical parameters are as follows:
- Length: 45.72m (standard track length)
- Width: 4.75-5.0m ( customizable )
Surface Hardness: Shore D 65±3
- Service Life: ≥10 years (under regular maintenance)
- Application scenarios: professional sports venues, university training bases, commercial curling experience centers, etc.

4. Industry Application Case: Curling Training Base Project in a Certain Province

1. Project Background
The Sports Bureau of a certain province needs to build an international-standard curling training track to prepare for the National Winter Games. Hebei Junchi provides a customized solution based on the site conditions (indoor temperature -10℃ to 5℃, humidity 40%-60%), including track size adjustments and heating system upgrades.

2. Implementation process
- Basic Construction: Concrete pouring + moisture-proof layer laying, ensuring ground flatness error ≤2mm.
- Track Installation: Using laser leveler for calibration, single track assembly time ≤2 hours, overall installation period of 15 days.

3. Technical Effect Review
After project delivery, the track surface smoothness and ice pattern uniformity have all passed the national sports equipment supervision and inspection center's testing. Training feedback shows an improvement of 30% in the stability of the curling sliding path, and the athletes' training efficiency has significantly increased. Currently, the track has hosted 3 provincial-level events and trained over 200 students.

V. Summary of Technical Advantages and Industry Experience

The core advantage of Hebei Junchi Curling Track technology lies in the triple guarantee of "material + technology + service."
- Material end: Collaborating with well-known domestic chemical companies to develop special HDPE materials, balancing wear resistance and low-temperature toughness.
- Process end: Introducing CNC machine tools and laser engraving technology, achieving millimeter-level control of manufacturing precision.
- Server-side: Provide full-process support from site design to after-sales maintenance, ensuring the long-term stable operation of the track.

After nearly 10 years of technical accumulation, Hebei Junchi has established a mature system for curling track manufacturing. Its products not only meet domestic demand but are also exported to cold regions such as Mongolia and Russia, making it one of the representative enterprises in the sports equipment industry for technological innovation.
