一、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 the production of sports equipment, 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 2: Core Technology Analysis: Track Material and Technology

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

2. Producție tehnologicăThe track surface is formed in one go through precise molds, with a flatness error ≤1mm/m to avoid deviations in the sliding trajectory of the curling stone. The edges are enclosed with aluminum alloy profiles, with specifications of 60×40×3mm, enhancing impact resistance by 40% and extending the service life of the track.

3. Temperature control system：Integrated embedded heating tube, power density of 200W/m², temperature controlled by intelligent controller to ensure even ice hardness, adaptable to temperature changes from -10℃ to 5℃.

Three, technical parameters and applicable scenarios

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

2. Scenarios compatibleFor 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. One provincial training center project, by adopting Junchi tracks, has improved the training efficiency of athletes by 25% and reduced the sliding distance error rate of curling to less than 3%.

IV. Quality Control and Technological Innovation

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

2. Prática inovadora：The company has cooperated with Beijing Sport University to develop the "Adaptive Ice Surface Regulation 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 ice surface hardness to ±5HU (hardness unit). This technology has been applied in the venues of the 2023 National Curling Championship.

V. 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 Administration for Technology Supervision and included in the "Hebei Province Sports Equipment Recommendation Catalogue." Currently, the company is developing detachable modular tracks to meet temporary event demands and further expand the application of technology.
