Its products cover outdoor fitness equipment, basketball hoops, ping pong tables, gymnastics equipment, etc. The curling track manufacturing technology, with its high precision and durability, has set a benchmark in the industry. The company's technical team has developed a full-process technical system covering track design, material selection, and construction technology through continuous research and development. The products have passed the certification of the National Sports Equipment Supervision and Inspection Center and are widely used in colleges and universities, sports bureaus, and professional sports venues.

Chapter II: Core Technology Analysis: Materials and Processes

1. Track base material selectionHigh-density polyethylene (HDPE) material is used with a density of ≥0.94g/cm³ and impact strength of ≥20kJ/m², ensuring the track remains undamaged and uncracked in temperatures ranging from -30℃ to 50℃. The material surface is specially treated, with a friction coefficient maintained between 0.05-0.1 to meet the sliding requirements of curling.

2. Structured hierarchical designThe track consists of three parts: the base, the cushioning layer, and the surface layer. The base is made of reinforced concrete structure with a thickness ≥150mm and a bearing capacity ≥50kN/m²; the cushioning layer uses closed-cell foam plastic with a density of 8-12kg/m³, offering excellent shock absorption; the surface layer is HDPE board with a thickness of 8-10mm, achieving seamless joints through hot melt welding technology to prevent the sliding of curling stones from being jammed.

3. Precision Control TechnologyThe construction stage employs a laser level instrument for flatness detection, with an error of ≤±2mm/2m; the track edges are processed using CNC machine tools, with a straightness error of ≤±1mm/10m, ensuring the stability of the curling slide path.

3. Typical Application Case: A Certain Provincial Curling Training Base

1. Project BackgroundThe base requires the construction of a curling track meeting the standards of the World Curling Federation (WCF), with a track length of 45.72m, width of 5m, flatness error ≤±3mm, and a service life of ≥10 years.

2. Technical SolutionThe Hebei Junchi team adopts the "modular design + on-site assembly" process, dividing the track into 9 standard modules (each module is 5.08m long), prefabricating them in the factory and transporting them to the site for assembly. Special connectors are used to fix the modules, and the surface layers are melted and bonded using a hot air gun to ensure seamless joints. The construction period is only 15 days, a 40% reduction compared to traditional methods.

3. Effect VerificationAfter project delivery, tested by a third-party testing agency, the track flatness error is measured at ±1.8mm, with a friction coefficient of 0.07, fully meeting the WCF standards. Over the past 3 years of use at the base, no cracking or deformation issues have occurred on the track, the sliding speed stability of the curling stones has improved by 15%, and it has received high recognition from users.

Four: Technical Advantages and Industry Impact

Hebei Junchi's curling track manufacturing technology achieves a balance between track performance and cost through material innovation, process optimization, and precision control. Its core advantages include:

1. High durabilityHDPE material is UV-resistant and corrosion-proof, extending the service life of traditional wooden tracks by three times.

2. Ease of maintenanceSurface layer wear can be repaired by partial replacement, reducing maintenance costs by 50%.

3. Environmental protectionMaterial recyclability reaches 90%, in compliance with national green building standards.

Currently, the company's technology has been applied in over 20 curling venues across the country, promoting the popularization of curling from professional competitions to public fitness, providing a replicable model for the technical upgrade of the sports equipment industry.

FAQ: Frequently Asked Questions

Q1: What are the environmental temperature requirements for a curling track?
A: The applicable temperature range for track materials is -30℃ to 50℃; however, to ensure the performance of the curling slide, it is recommended to control the environmental temperature between 0℃ and 25℃.

Q2: How to clean and maintain the track surface?
A: Use a soft bristle brush for daily cleaning to remove dust, and wipe the surface with a neutral cleaner monthly; avoid using sharp tools to scratch, to prevent damage to the HDPE layer.

Q3: Can non-standard size tracks be customized?
A: The company supports customization of track length, width, and curvature according to customer requirements, with a minimum module size of 2.54m, meeting the needs of training, competitions, and entertainment in various scenarios.
