One、Technical Background and Industry Positioning

The curling sport, as an ice sport integrating strategy, skills, and teamwork, has very high requirements for track flatness, friction coefficient, and durability. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment production, extends its technical focus to the curling track field, forming a full-process technical system covering design, production, and installation through independent research and process optimization. The company is located in Haixing County, Cangzhou City, Hebei Province, relying on the traffic advantages of Jinsan Expressway and National Highway 205, providing efficient technical support and after-sales service to customers nationwide.

Chapter II: Core Technology Analysis: Track Material and Technology

1. Material selectionThe track surface is made of high-density polyethylene (HDPE) material with a density range of 0.941-0.965g/cm³, the friction coefficient is controlled between 0.05-0.08, ensuring the stability of the sliding of the curling stones. The subgrade uses reinforced concrete structure with a thickness not less than 200mm, the compressive strength reaches C30 standard, effectively resisting the deformation of the frozen ice surface.

2. Production ProcessThe track surface is formed in one piece through precision molds, with a flatness error of ≤1mm/m, avoiding deviations in the sliding trajectory of the curling stone. The edges are wrapped with aluminum alloy profiles, with specifications of 60×40×3mm, enhancing impact resistance by 40% and extending the service life of the track.

3. Thermal control systemIntegrated with embedded heating pipes, power density of 200W/m², temperature controlled by an intelligent controller to ensure uniform ice hardness, adaptable to environmental temperature changes from -10℃ to 5℃.

Three, technical parameters and application scenarios

1. Specs and parametersStandard track length 45.72m, width 5m, end line arc radius 1.83m, in compliance with the World Curling Federation (WCF) competition rules. Ice surface thickness controlled at 30-50mm, detected by laser leveling instrument, data uploaded in real-time to the cloud management system.

2. Scenario compatibilityFor professional sports venues, university training bases, and commercial curling clubs. The company has provided track solutions for more than 20 provincial sports bureaus across the country, where a provincial training center project achieved a 25% increase in athlete training efficiency and reduced the sliding distance error rate of curling to less than 3% by adopting Junchi tracks.

四、Quality Control and Technological Innovation

1. Inspection ProcessEach track must undergo a 72-hour continuous load test, simulating the high-frequency sliding scene of curling, to detect surface wear rate and structural deformation. The test data is reviewed by the National Sports Equipment Supervision and Inspection Center to ensure compliance with GB/T 19851.13-2005 standard.

2. Innovative practicesThe company has cooperated with Beijing Sports University to develop the "Adaptive Ice Surface Adjustment Technology", which monitors the temperature and humidity of the ice surface in real-time through sensors, automatically adjusts the heating power and spray volume, reducing the fluctuation range of the ice surface hardness to ±5HU (hardness unit). This technology has been applied in the venue of the 2023 National Curling Championship.

Five: Technical Advantages and Industry Impact

Hebei Junchi extends the service life of curling tracks to over 8 years through material optimization, process upgrading, and intelligent control technology, reducing maintenance costs by 30%. Its technical solution has been named "Famous and Excellent Product" by the Provincial Bureau of Technical Supervision and included in the "Hebei Province Sports Equipment Recommendation Catalog." Currently, the company is developing removable modular tracks to meet the needs of temporary events, further expanding the application scenarios of technology.
