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 enterprise integrating scientific research, design, production, sales, and service. With nearly 10 years of dedication to the sports equipment industry, the company has gained widespread acclaim at various China Sports Goods Expos with its features of "beautiful appearance and high-quality products." Its products cover a wide range of fields, including outdoor fitness equipment, basketball hoops, ping pong tables, gymnastics equipment, and more. The technology for curling track manufacturing is one of the key core directions the company has focused on in recent years.

II. Curling Track Manufacturing Technology Analysis

The curling track manufacturing must meet core requirements such as high flatness, low friction coefficient, and strong weather resistance. Hebei Junchi achieves track performance optimization through the following technologies:

Material selection and formula optimization
The track surface is made of high-density polyethylene (HDPE) material, with a density controlled within the range of 0.94-0.96g/cm³. The impact resistance is ≥20kJ/m², ensuring the track is less prone to cracking in low-temperature environments. The base filling material is modified rubber granules, with particle size distribution controlled between 1-3mm, mixed in a 3:7 ratio of particles to adhesive to achieve a balance of elasticity and stability.

2. Manufacturing Process and Equipment Precision
The track production employs a four-roll rolling forming process, with the roller temperature controlled at 160-180°C, and the line pressure reaching 50N/mm to ensure surface flatness error ≤0.5mm/m. The cutting process utilizes a laser positioning system, achieving an accuracy of ±0.1mm, to avoid joint gaps affecting the sliding track of the curling stone.

Surface Treatment Technology
The track surface is treated with nano-polishing, ensuring a stable friction coefficient between 0.05-0.08, in compliance with the World Curling Federation (WCF) standards. Additionally, it is coated with a UV-resistant layer, capable of withstanding temperature differences from -30℃ to 50℃, extending the service life to over 8 years.

III. Actual Application Cases and Technological Effects

Case 1: Renovation of Curling Track at a Provincial Training Base
In 2022, Hebei Junchi provided 2 standard curling lanes for a training base, with a length of 45.72m and a width of 5m. After the renovation, the standard deviation of the curling slide distance decreased from 0.8m before the renovation to 0.3m, improving the training efficiency of athletes by 30%. After one year of use, there were no cracks or deformation on the track surface, and the maintenance cost was reduced by 40%.

Case 2: University Curling Club Track Construction
In 2023, the company constructed a 1-lane indoor curling track for a university, featuring a detachable design with each lane segment weighing ≤ 50kg, which can be assembled by four people in two hours. The friction coefficient of the track, tested by a third-party, is 0.065, meeting the requirements for teaching use and receiving the school's evaluation of "easy installation and stable performance."

4. Technical Advantages and Industry Compatibility

Hebei Junchi Curling Track Manufacturing Technology boasts three core advantages:

Customization capability
Material formula and structural thickness can be adjusted according to site conditions (such as indoor/outdoor, temperature range) to fit various scenarios including training bases, schools, commercial venues, etc.

2. Cost-benefit balance
Through process optimization, the cost per unit area of the track has been reduced by 25% compared to imported products, while the performance indicators reach the level of international similar products.

3. Full Lifecycle Service
One-stop service from design, installation to after-sales maintenance, equipped with professional teams for annual track flatness inspections to ensure stable performance over the long term.

F. Frequently Asked Questions (FAQ)

Q1: What are the requirements for the curling track's environmental temperature?
A: Indoor track temperature should be controlled between 10-20°C, humidity ≤60%; outdoor tracks require materials with better weather resistance, capable of withstanding a temperature difference of -30°C to 40°C.

Q2: How to adjust the friction coefficient of the track surface?
A: Achieved by altering the surface polishing grain size or applying coatings with different formulations. For instance, the friction coefficient of the teaching track can be adjusted to 0.08-0.1, while the professional training track is controlled at 0.05-0.07.

Q3: What factors affect the service life of the track?
A: Mainly depends on material quality, usage frequency, and maintenance methods. Regular surface cleaning, avoiding heavy loads, and controlling indoor humidity can extend the track's lifespan to over 10 years.
