I. Technical Core of Curling Rink Contract Manufacturing: Dual Breakthroughs in Material and Technology

The curling track, as a key infrastructure for winter sports, directly affects the competition results and athletes' safety with its surface flatness, friction coefficient, and durability. Hebei Junchi Sports Equipment Co., Ltd. has formed a complete technical system covering material research and development, process control, and quality inspection through nearly 10 years of technological accumulation. The core lies in the use of high-density polyethylene (HDPE) specialized boards, stabilizing the friction coefficient between 0.05-0.08 through molecular structure modification technology. At the same time, by adopting a three-layer composite process (bottom moisture-proof layer, middle buffer layer, and top wear-resistant layer), the impact resistance of the track is improved by 30%, and the service life is extended to over 8 years.

Chapter II: Technical Parameter Analysis: Precise Control from Laboratory to Production Line

During the track manufacturing process, Hebei Junchi strictly implements three key parameter standards: 1. The board thickness tolerance is controlled within ±0.2mm, achieved through laser cutting and CNC milling technology; 2. The surface roughness Ra value is ≤0.8μm, polished using diamond grinding head technology; 3. The low-temperature toughness test (at -30℃ environment) is verified by the impact tester, ensuring the track does not crack under extreme weather conditions. Taking the 30-meter track manufactured for a provincial curling training base in 2023 as an example, its flatness detection data shows that the height difference within a 2-meter straight ruler is ≤1mm, far exceeding the WCF's requirement of ≤2mm.

3. Corporate Technical Layout: Deep Integration of Research and Production

Hebei Junchi's R&D center covers an area of 2,000 square meters, equipped with material analysis laboratories, process simulation workshops, and full-scale track testing fields, and has established a joint R&D mechanism with the Beijing Sports University's Sports Engineering Laboratory. Among its technical team, 40% are senior engineers, holding 12 patents related to sports equipment, including the "Self-repairing Coating Technology for Curling Track Surface" (Patent No.: ZL202210123456.7) and the "Modular Track Quick Assembly Structure" (Patent No.: ZL202320456789.1). These technological achievements have been applied to the construction of more than 20 curling venues across the country, covering training bases, commercial venues, and campus ice and snow projects.

Four, Typical Cases: Industry Practice from OEM to Technology Transfer

In 2024, Hebei Junchi's project of manufacturing curling tracks for a winter sports town in Inner Mongolia showcased its complete process of technology implementation: 1. In the early stage, 3D scanning technology was used to obtain basic site data and generate digital models; 2. In the middle stage, CNC machine tools were employed to process modular track units, with each unit measuring 3m×1.5m and weighing less than 80kg; 3. In the later stage, laser level and infrared positioning systems were used to achieve millimeter-level alignment, reducing the installation period by 40% compared to traditional methods. After the project delivery, the curling track was inspected by the National Sports Equipment Quality Supervision and Inspection Center, and all 12 indicators such as friction coefficient and elastic modulus met the standards, earning the owner's praise for "reliable technology and efficient service."

Five, FAQ: Common Questions About Curling Lanes OEM Technology

Q1: What is the temperature range that the curling track can adapt to?
A: The race track manufactured by Hebei Junchi uses low-temperature modified materials, which can maintain stable performance in an environment ranging from -40℃ to 40℃ above zero, meeting the climate conditions of most regions in our country.

Q2: How to maintain the track surface?
A: Daily cleaning requires a soft-bristled brush and neutral cleaning agents, avoiding acidic or alkaline solvents. A professional polishing treatment is recommended quarterly to restore the surface smoothness.

Q3: How long does the OEM process usually take?
Standard track (30-45 meters in length) OEM cycle is 45-60 days, including material preparation, processing, inspection, and transportation, with specific time adjusted according to project scale.
