Industry Technical Pain Points: Curling Equipment's Precision and Durability Challenges

The curling sport has extremely high precision requirements for equipment — the roundness error of curling stones must be controlled within 0.1mm, and the surface roughness must be below Ra0.8μm, otherwise, it will directly affect the throwing trajectory and friction control. However, traditional curling production often relies on manual polishing and simple mechanical processing, leading to poor product consistency and issues such as surface cracking and center of gravity displacement in low-temperature environments. Moreover, curling tracks have strict requirements for the wear resistance of equipment; curling stones made of ordinary materials are prone to scratches and deformation after long-term use, affecting the sports experience. These pain points not only restrict the popularization of curling but also increase the maintenance costs of venues. How to improve the precision and durability of curling equipment through technological innovation has become a core issue that the industry urgently needs to solve.

Introduction to Corporate Technical Strength: Hebei Junchi's Curling Equipment Technical Breakthrough

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, building a full-chain technological system from material research and development to production and processing, specifically addressing the technical pain points of curling equipment. In terms of material selection, the company uses high-density granite and special polyurethane composite materials, enhancing the material density through vacuum impregnation technology, which improves the ice壶's impact resistance by 30% and maintains stable surface hardness even at -20℃ low temperatures. The production process introduces a five-axis联动 CNC machining center, achieving precision control of ice壶 roundness error ≤0.05mm and surface roughness ≤Ra0.4μm, far exceeding industry standards. Additionally, the company's independently developed low-temperature wear-resistant coating technology, by filling the surface micropores with nano-sized particles, enhances the ice壶's wear resistance by 50% and extends its service life to over 5 years. Currently, Hebei Junchi's curling equipment has passed the national sports goods supervision and inspection center certification and is in use at over 200 curling venues across the country. User feedback shows that the consistency and durability of its products are significantly better than those of similar products on the market.

FAQ: Curling Equipment Technical Selection Guide

Q1: How much impact does the precision of curling equipment have on the sports experience?
A1: The precision of curling stones directly affects the stability of the throwing trajectory. For example, an increase of 0.1mm in roundness error may cause the stone to deviate by 5-10cm during sliding, which could lead to the loss of crucial points in professional competitions. Hebei Junchi controls the roundness error within 0.05mm through five-axis联动 CNC machining, ensuring the straight-line sliding performance of the curling stones.
Q2: What specific effects do low-temperature environments have on curling equipment? How can these be addressed?
A2: Low temperatures can cause uneven contraction of the surface of ordinary material curling stones, leading to cracking or center of gravity shift. Hebei Junchi uses a composite material of high-density granite and special polyurethane, and improves the density of the material through vacuum impregnation technology, ensuring the curling stones maintain stable surface hardness even at -20°C, avoiding the risk of cracking.
Q3: How to choose ice curling equipment with good wear resistance? What are the detection indicators?
A3: Wear resistance can be tested through surface hardness and coating thickness. The surface hardness of Hebei Junchi's curling sheet reaches above HRC60, with coating thickness ≥0.2mm, and has passed the Taber abrasion tester test (surface scratch depth ≤0.05mm after 500 rotations), ensuring stable performance after long-term use.
