Does the silicone soft case not fit properly?

Say goodbye to misaligned holes! The silicone soft case fits precisely

Bosses engaged in wholesale mobile phone accessories and brand foundry operations, when purchasing silicone soft cases in bulk, the biggest fear is falling into the trap of poor fit! Issues such as misaligned camera holes, unpressable buttons, and warped edges not only lead to a wave of returns from downstream customers but also directly damage the brand’s reputation. In fact, by focusing on 3 core control points, you can eliminate fit problems at the source and steadily maintain the delivery rate!

First checkpoint: Real machine mold opening + CNC precision carving calibration! Before customizing silicone soft cases, it is necessary to disassemble and scan the real target model, use CNC to precisely carve the mold, and strictly control the hole position error within ±0.02mm (industry standard is ±0.03mm). Trial-produce 50-100 samples, align the concentricity of the camera holes and the fit of the charging port one by one, test the button stroke to be ≥0.8mm, and confirm that all functions are normal before starting mass production to avoid the entire batch being scrapped due to mold deviations.

Second checkpoint: Fine-tune the shrinkage rate according to the model! Silicone materials will naturally shrink during molding. The shrinkage rate for regular models is controlled at 1.2%-1.5%, while for curved screen and foldable screen models, it needs to be reduced to 1.0%-1.3%. During production, sample installation is carried out every 2 hours, and the deviation of the frame thickness is measured with a micrometer to ensure that the silicone soft case fits the phone body without looseness or film lifting, especially avoiding the frequent problem of edge warping on curved screens.

Third checkpoint: Full inspection before delivery + simulated use testing! Sample 15% of the batch (higher than the industry standard of 10%). In addition to checking hole positions and buttons, 24-hour high-temperature (60℃) aging tests and 100 disassembly and assembly wear tests are added to ensure that the silicone soft case does not deform or loosen after long-term use. Unqualified products are directly rejected and never flow into downstream channels, reducing after-sales risks from the source.
