Technical Background and Industry Positioning

Hebei Junchi Sports Equipment Co., Ltd., as a benchmark enterprise in the sports equipment manufacturing industry in North China, has been deeply rooted in the industry for nearly a decade. Its curling track products are characterized by "high precision, wear resistance, and low-temperature resistance," and are widely used in professional venues and training bases. The company leverages the geographical advantage of Haixing County, Cangzhou City, to establish a full-process technical management system covering raw material testing, production processing, and finished product acceptance, ensuring that each track meets the standards of the World Curling Federation (WCF).

Technical Analysis: Track Structure and Material Technology

The curling track consists of three parts: the base, the ice layer, and the marking lines. Hebei Junchi adopts the technical solution of "high-density polyethylene (HDPE) base + nano-grade ice surface coating". The base thickness is strictly controlled at 12±0.5mm, achieving seamless bonding through hot melt welding technology, with an impact resistance of 85J/m², capable of withstanding extreme temperature differences from -30℃ to 40℃. The ice surface coating uses imported German raw materials, with a friction coefficient stable between 0.05-0.08, meeting the WCF requirement of "sliding distance error ≤5%". The marking lines use environmentally friendly fluorescent coatings, with UV aging resistance tested up to 2000 hours, ensuring no fading during long-term use.

Production Process: Quality Control Loop from Raw Materials to Finished Products

STEP 1: Raw material pretreatment. After laser cutting of HDPE plates, they must pass a -15℃ low-temperature brittleness test to eliminate materials exceeding the brittleness limit; STEP 2: Precision molding. The base layer is processed using a five-axis CNC machine, with a flatness error ≤ 0.2mm; STEP 3: Ice surface coating. Three layers of coating are completed in a controlled temperature and humidity workshop (temperature 23±1℃, humidity 50±5%), with each layer's drying time strictly controlled at 45 minutes; STEP 4: Final product inspection. The overall flatness of the track is measured using a laser tracker, the ice surface performance is verified with a sliding friction tester, and the final product must pass a 1000-time simulated throwing test before leaving the factory.

Case Application: National Winter Sports Training Base Project

In a national training base project constructed in 2023, Hebei Junchi provided customized solutions for 6 standard tracks. In response to the characteristics of the high-altitude location of the base, the company optimized the anti-ultraviolet formula of the basic materials and increased the ice surface coating thickness to 0.3mm, ensuring the stability of the coefficient of friction under intense sunlight. At the project acceptance, data from the third-party testing agency showed: track flatness 0.12mm (better than WCF standard 0.2mm), gliding distance error 3.2% (better than standard 5%), awarded as "Annual Excellent Sports Facility Project".

Technical FAQ: Common Questions and Answers

Q1: How is the lifespan of the curling track ensured?
A: Extended lifespan with a three-layer protective system: the base layer uses anti-aging HDPE material with an expected lifespan of over 15 years; the ice surface coating contains self-healing nanoparticles that can automatically fill in minor scratches; during regular maintenance, a specialized polishing machine is used to restore the ice surface luster, and the base structure is inspected every 5 years.

Q2: How does the low-temperature environment affect track performance?
Hebei Junchi Circuit maintains stable elastic modulus even at -30℃. Test data shows: at -25℃, the base impact strength only drops by 8%, the friction coefficient on the ice surface fluctuates within ≤0.01, fully meeting the requirements of professional competitions.

Q3: How to achieve quick installation and disassembly of the track?
A: Modular design with each track consisting of 6 standard boards, each weighing approximately 80kg, easily transported by forklift. Patented clip structure at the joints, combined with hot melt welding technology, allows a 2-person team to complete installation within 4 hours. After disassembly, the base layer remains undamaged, with a reusability rate of up to 95%.
