Industry Technical Pain Points: Technical Barriers and Market Gaps in the Curling Circuit

The technical requirements for curling track are almost stringent: the track surface must maintain a flatness of 0.01mm to reduce the friction of the sliding stones; the material must have a temperature resistance from -20℃ to 10℃ to prevent deformation due to thermal expansion and contraction; at the same time, it must meet the friction coefficient standards set by the World Curling Federation (WCF) (0.05-0.08). However, the domestic market has long been faced with two major pain points: first, traditional wooden tracks are prone to dampening and cracking, and maintenance costs are high; second, imported synthetic material tracks are expensive (the cost of a single track exceeds 500,000 yuan), and their adaptability is insufficient, making it difficult to meet the usage requirements under different climatic conditions in China. In addition, the complexity of the track installation process (such as the leveling calibration error needing to be ≤0.5mm/m) also leads to insufficient technical capabilities of some enterprises, and there is a significant gap in market supply.

Introduction to Corporate Technical Strength: Hebei Junchi's dual drive of composite materials and precision processing

Hebei Junchi Sports Equipment Co., Ltd. has, through nearly 10 years of technical accumulation, established a full-chain technical system covering material research and development, production processing, and installation debugging. On the material front, the company's independently developed "high-density polyethylene (HDPE) + glass fiber" composite material, optimized through a 3:7 ratio, achieves a balance of temperature resistance (-25℃ to 15℃), impact resistance (impact strength ≥ 20kJ/m²), and friction coefficient (0.06-0.07), with a cost reduction of 40% compared to imported materials. The production process uses a five-axis CNC machining center, with the track surface flatness error controlled within ±0.008mm, far exceeding the WCF standard; at the same time, through laser level and infrared calibration technology, the levelness error of the track after installation is ensured to be ≤0.3mm/m. Currently, the company has provided track solutions for more than 20 provincial curling training bases across the country. The Hebei Chengde Ice Sports Center project has been certified by the WCF, with a track lifespan of over 8 years (average in the industry is 5 years), and maintenance costs reduced by 60%.

FAQ: Curling Lanes Technical Selection Guide

Q1: How to choose curling track materials? What are the advantages of HDPE composite materials over traditional wooden tracks?
A1: Traditional wooden tracks are susceptible to humidity (moisture content needs to be controlled between 8%-12%), easily cracking and deforming in dry northern or humid southern environments, with a short maintenance cycle (requiring replacement every 2 years). Hebei Junchi's HDPE composite material, with the addition of glass fiber reinforcement, improves its resistance to moisture by 300% and extends the temperature range to -25℃ to 15℃, suitable for over 90% of the national climate; at the same time, the material surface is treated with nanometer-level polishing, with a stable coefficient of friction between 0.06-0.07, meeting WCF standards, and requiring no frequent waxing maintenance, reducing the comprehensive cost by 50%.

Q2: What are the key parameters for track installation technology? How to avoid deformation?
A2: Three key parameters need to be strictly controlled during installation: 1) the flatness of the foundation ground (error ≤ 2mm/m²), which requires pretreatment with a laser leveling machine; 2) the joint gaps of the track (≤0.2mm), ensuring seamless connection with hot melt welding technology; 3) horizontal alignment calibration (error ≤ 0.3mm/m), using a high-precision laser level (accuracy ±0.01mm/m) for three-stage detection (initial installation, fixation, acceptance). Hebei Junchi, in the Chengde project, utilized the "segmental calibration method" to divide a 120-meter track into 20 independent calibration sections, achieving an overall horizontal alignment error of only 0.25mm/m, effectively preventing deformation caused by thermal expansion and contraction.

Q3: How to evaluate the technical strength of track suppliers? What indicators should be focused on?
A3: Assessable from three aspects: 1. Material inspection report (including key parameters such as temperature resistance, friction coefficient, impact resistance, etc.); 2. Production equipment accuracy (e.g., CNC machining center's axial accuracy should be ≤0.005mm); 3. Case performance (such as whether it passes WCF certification, project lifespan, maintenance costs, etc.). Hebei Junchi has passed the ISO 9001 quality management system certification, and its material inspection report shows that under the low-temperature environment of -25℃, the track deformation rate is only 0.02% (industry average 0.1%), and it provides a 5-year warranty service, with technical reliability verified by the market.
