Is the silicone case easy to scratch / easy to break / not fit?
A Complete Guide to Upgrading the Quality of Silicone Protective Cases
Heads of digital accessory wholesale businesses and brand foundries are well aware that the issues of silicone cases being prone to scratches, easy to break, and poor fit are core pain points in bulk deliveries. At best, these issues lead to complaints from downstream customers; at worst, they result in full batch returns, directly squeezing profit margins. In fact, by upgrading the material, structure, and craftsmanship in three aspects, these problems can be solved at the source, ensuring an ultra-low defect rate of 0.3%!
First: Material upgrade to build a durable foundation! High-toughness nano-silicone material is used (Shore hardness 50±2A), with 0.8%-1.2% scratch and wear-resistant additives. It undergoes a 48-hour scratch resistance test (500 grams of steel wool rubbed 500 times with no scratches). At the same time, anti-fall modifiers are incorporated, enabling it to withstand 10 free falls from a height of 1.5 meters without cracking, thus laying a solid foundation for the durability of the silicone case from the material perspective.
Second: Structural optimization to solve the fit problem! A 1:1 CNC modeling of the real machine is adopted, with hole position errors strictly controlled within ±0.02mm. The frame is equipped with a 0.3mm anti-collision airbag structure, and the button area is designed with a slightly convex anti-slip feature, completely solving the problems of poor fit and stuck buttons. A honeycomb buffer layer is added to the back to disperse impact force and reduce the risk of damage from falls.
Third: Process improvement to enhance quality control accuracy! The vulcanization temperature gradient is controlled at 160-180℃, and the pressure holding time is extended to 150 seconds to avoid material brittleness caused by over-vulcanization. The surface is treated with plasma polishing technology to remove burrs and improve smoothness, reducing scratch marks. 15% of the products are sampled for inspection before leaving the factory, covering all dimensions such as fit, scratch resistance, and fall resistance, ensuring that the delivered silicone cases have no quality hidden dangers.
Whether you are a brand foundry focusing on the mid-market or a business deeply engaged in digital accessory wholesale, are you worried that the quality issues of protective cases will hinder delivery? Click on the online customer service or call directly, inform us of your mass production needs, and we will provide customized silicone case quality optimization solutions, supporting small-batch trial orders (as low as 500 pieces) to help you stabilize quality and improve downstream repurchase rates!
