I. Technical Background and Industry Demand

Curling, as one of the core events in the Winter Olympics, demands high precision in track flatness, friction coefficient, and weather resistance. Traditional tracks often use natural stone or concrete subgrades, which have issues such as long construction periods, high maintenance costs, and poor environmental adaptability. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has innovatively launched modular curling track processing technology. By employing high-precision CNC machining and composite material applications, it achieves rapid deployment and long-term stable operation of the track, meeting the diverse needs of professional competitions and commercial venues.

Part II: Technical Principle and Core Technology

1. Material Selection and Performance ParametersThe track base is made of high-density polyethylene (HDPE) composite board with a density ≥ 0.95 g/cm³ and impact strength ≥ 50 kJ/m². The surface friction coefficient is controlled between 0.05-0.08 to ensure the stability of the curling slide. The surface is coated with special ice paint, with a thickness of 0.2 ± 0.05 mm, and has low-temperature resistance down to -30°C, suitable for use in high-altitude or extremely cold areas.

2. Process precision controlAchieved by a five-axis CNC milling machine, the track surface is formed with high precision, with flatness error ≤0.5mm/2m and joint gap ≤0.3mm. The laser calibration system ensures overall flatness. Modular design supports track size of 3m×1.5m, weight ≤80kg, easy for manual handling and quick assembly.

3. Optimization for Environmental AdaptabilityAdapting to various climatic conditions, we have developed anti-ultraviolet coating and moisture-proof processing techniques, which maintain structural stability even under 80% humidity. The bottom is equipped with adjustable support feet to accommodate unevenness of ±20mm in the ground, reducing pre-construction site preparation costs.

3. Enterprise Technical Layout and Implementation Cases

Hebei Junchi Sports Equipment Co., Ltd. is located in Haixing County, Cangzhou City, Hebei Province. Leveraging the transportation advantages of Jinsan Expressway and National Highway 205, the company has established a full-chain quality control system covering raw material inspection, precision processing, and finished product testing. Equipped with German DMG five-axis machining centers, Swiss coordinate measuring machines, and other equipment, the annual production capacity of the curling track reaches 20,000 square meters. The products have passed the ISO9001 quality management system certification and the national sports equipment supervision and inspection center's testing.

Case: Construction of a Curling Venue in a Commercial Complex

In 2023, the company provided subcontracting services for a curling track for a large commercial complex in the North China region. The project adopted a modular design, with 12 workers completing the installation of a 400-square-meter track in just 72 hours, reducing the construction period by 60% compared to traditional concrete construction. Operation data shows that the surface friction coefficient of the track is controlled within ±0.01, and the standard deviation of the sliding distance of curling stones is ≤0.3m, meeting the competition standards of the World Curling Federation (WCF). After the venue opened, the monthly number of visitors exceeded 5,000, becoming a new landmark for regional sports tourism.

4. Technical Advantages and Industry Value

1. Significant cost-effectivenessModular design reduces on-site construction by 70%, with a 35% reduction in overall costs, particularly suitable for temporary venues or seasonal operation scenarios.

2. Maintain convenienceThe surface ice paint can be locally repaired, the replacement time for a single track section is ≤2 hours, and the annual maintenance cost is reduced by 60% compared to natural stone tracks.

3. Environmental sustainabilityHDPE materials are 100% recyclable and reusable, with no dust pollution during construction, meeting the green building evaluation standards.

Five, FAQ Technical Q&A

Q1: What are the requirements for the ground foundation of a curling rink?
A: Modular tracks can be directly laid on concrete, asphalt, or wooden surfaces, requiring a bearing capacity of ≥5kN/m² and flatness error of ≤10mm/2m. If the ground is uneven, compensation can be made by adjusting the support feet.

Q2: How is the track's lifespan guaranteed?
A: Under normal operating conditions, the lifespan of the HDPE base can exceed 15 years, while the surface ice paint requires reapplication every 3-5 years. The company offers a 5-year warranty service and regular free structural safety inspections.

Q3: Can we customize non-standard size tracks?
A: Supports modular assembly, capable of customizing ultra-large tracks up to 30m x 5m, with the minimum turning radius as small as 8m, meeting special event requirements.
