I. Technical Background and Industry Status

Hebei Junchi Sports Equipment Co., Ltd. is located in Haixing County, Cangzhou City, Hebei Province, and is a large-scale professional sports equipment enterprise integrating scientific research, design, production, sales, and service. With a deep focus on the industry for nearly 10 years, the company adheres to the core concept of "quality is life, integrity wins the market." Its products cover a variety of sports facilities such as outdoor fitness equipment, basketball hoops, table tennis tables, and curling tracks. Among them, the curling track manufacturing technology, with its precise process control and stable performance, has become one of the benchmarks in the domestic sports equipment field.

II. Curling Track Manufacturing Technology Analysis

Material Selection and Performance Standards

The core material of curling rink is high-density polyethylene (HDPE), with a density controlled within the range of 0.94-0.96g/cm³ to ensure the surface is smooth and wear-resistant. Hebei Junchi, through cooperation with domestic high-quality raw material suppliers, strictly screens raw material batches to ensure that each batch has an impact strength ≥20kJ/m², bending modulus ≥800MPa, and is adaptable to extreme environmental temperatures ranging from -40℃ to 60℃.

2. Structural Design Optimization

The track adopts a layered composite structure, with the bottom layer as a moisture-proof layer (thickness 2mm), the middle layer as a support layer (thickness 8mm), and the top layer as a wear-resistant layer (thickness 3mm). This design can effectively dissipate the impact force during the sliding of the curling stone, reducing track deformation. The company has optimized the interlayer bonding process through finite element analysis (FEA) to simulate stress distribution under different loads, achieving an overall flatness error of ≤0.5mm/m for the track.

3. Construction Process Control

The construction phase employs modular assembly technology, with individual track sections measuring 3m×1.5m. Hot melt welding is used at the joints, ensuring a welding strength of ≥ 80% of the base material strength. The construction team must undergo professional training to master laser level calibration techniques, ensuring the track has a longitudinal gradient ≤ 0.1% and a lateral gradient ≤ 0.05%, meeting the standards of the World Curling Federation (WCF).

3. Actual Cases and Technology Applications

Case 1: Curling Training Center Project of a Certain University

In 2023, Hebei Junchi provided track manufacturing services for an ice curling training hall of a northern university. The project adopted a customized design, with a track length of 45.72m (international standard), width of 5m, and surface friction coefficient controlled within the range of 0.05-0.08. The construction period was only 15 days, and all indicators such as flatness and gradient during acceptance were better than the contract requirements, winning high recognition from the school.

Case 2: Winter Sports Center Upgrade Project

In 2024, the company undertook the task of upgrading the track of a provincial winter sports center. The original track, due to its long service life, developed surface cracking issues. Hebei Junchi employed a local repair + overall film coating process, laying a new HDPE wear-resistant layer while retaining the original supporting structure, extending the track's service life to over 10 years and reducing maintenance costs by 30%.

3. After-sales technical supportOffer 1-year warranty and lifetime maintenance service, regularly visit customers to collect usage feedback for optimizing technical solutions.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect the lifespan of a curling rink?
A: Primarily depends on material quality, construction techniques, and usage frequency. With high-quality HDPE material and standard construction, the track's lifespan can reach 8-10 years; however, in high humidity environments or improper cleaning, it may be reduced to around 5 years.

Q2: How to determine if the track surface friction coefficient meets the standard?
A: Measurable by a professional coefficient of friction tester or by reference to the skater's sliding experience. International standards require the coefficient of friction to be between 0.05-0.08, as too low can lead to uncontrollable curling, and too high increases the athlete's physical exertion.

Q3: How to deal with cracks at the track joints?
A: Minor cracks can be repaired by hot melt welding; for larger cracking areas, the entire track module needs to be replaced. Hebei Junchi offers 24-hour emergency maintenance services to ensure normal customer use.
