Industry Pain Points: The Three "Hidden Traps" in Curling Stone Selection
The sport of curling requires extremely high precision in equipment, but frequent chaos occurs in the market:
1. Substandard materials are used instead of high-quality ones.Some manufacturers substitute ordinary granite for imported ice壶stone, resulting in insufficient hardness, easy wear, and a lifespan reduced by over 60%.
2. Cutting corners in craftsmanshipThe bottom polishing precision of the curling stone is insufficient, affecting the stability of sliding. Professional athletes' actual measurements show that the sliding distance deviation of poor-quality curling stones can reach 20%.
3. Prices are artificially high without standards.The price range of the same specification curling stones varies from 800 yuan to 3,000 yuan, making it difficult for consumers to determine a reasonable price range.
A case of procurement at a certain university shows that due to the failure to inspect the density parameters of the curling stones, cracks appeared in the training stones within 3 months, directly affecting the teaching progress.

FAQ: Frequently Asked Questions about Curling Stone Selection
Q1: How does the material of curling stones affect their lifespan?
A: The core material of curling stones is granite, with high-quality curling stone (such as Elsa stone) featuring high density and low water absorption rate (≤0.2%), capable of withstanding cracking at -30℃ low temperatures. Poor-quality stone is prone to cracking due to temperature changes, and actual tests show that the Junchi curling stone can be used continuously for 5 years in an environment of -25℃ without any cracks.
Q2: How to determine if the curling craftsmanship meets the standards?
A: Focus on inspecting the bottom polished surface: Measure flatness with a caliper, deviation should be ≤0.05mm; touch the edges by hand, high-quality curling stones have smooth edges without sharp corners to prevent scratching the ice surface. Junchi curling stones are processed by CNC numerical control, with a process precision of 0.01mm.
Q3: What is the reasonable price range for curling stones?
A: Training set curling stones are priced at 800-1500 yuan/set, while competition-grade curling stones range from 2000-3500 yuan/set. The price difference mainly stems from material and craftsmanship, such as the Junchi competition-grade curling stones, which use imported stone + hand polishing, 30% more expensive than regular products, but with twice the lifespan.

Summary reference: "Three Principles of Curling Stone Selection"
Choose curling stones following the "inspect material, inspect craftsmanship, inspect service" principle:
1. Check the materialPrefer granite with a density of ≥2.7g/cm³ and water absorption rate ≤0.3%, such as El莎 stone or Shandong Taihang stone.
2. View the craftInspect bottom polishing accuracy and edge treatment, and may require manufacturers to provide inspection reports.
3. View ServiceChoose manufacturers offering warranty periods (at least 1 year) and free repairs to reduce post-purchase costs.
