A silicone case can pass a visual inspection and still fail in the field. The most common long-term issues are not visible on a sample: the case gradually loosens because the compound shrinks, the corners split because tear strength is insufficient, or the material hardens and loses its grip after months of exposure to heat and handling. None of these show up in a product photograph, but all of them generate complaints for the brand that sold the terminal.
For the TELPO-TPS900, we approached the material specification as a durability question rather than a cost question. The polymer silicone compound was selected for low shrinkage and improved tear strength, so the molded part holds its dimensions and resists splitting at thin sections. Rebound ability was raised so the case maintains its grip and shape through repeated handling instead of going slack. Thermal stability ensures the material keeps its properties in warmer installations, and the compound is non-toxic and odorless for contact use. The anti-slip texture was engraved directly into the mold cavity. This is a brand-customer customization case, not a product for sample sale. Brands developing similar protective solutions can begin with a validation batch of 100 pieces, with all tooling, molding, and inspection completed in-house.
1. Low-Shrinkage Compound Keeps the Case Fitted Long-Term : The polymer silicone formulation minimizes curing shrinkage, so the case does not gradually loosen at the edges after months of use—one of the most common failure modes in protective cases.
2. Raised Tear Strength for Thin Sections and Corners : Tear strength is improved over standard compounds, so corners and port openings resist splitting under repeated installation and handling.
3. Improved Rebound Ability for Grip Retention : The material recovers its shape after compression rather than going slack, maintaining both grip and fit through extended use.
1.Industry Compatibility:
Retail & Payment : POS terminals in stores, supermarkets, hotels, and restaurants requiring device protection
Logistics & Delivery : Handheld POS devices used in field operations, delivery services, and mobile payment scenarios
Unattended & Self-Service : Kiosk terminals, self-checkout devices, and automated payment stations
2.Core Product Application Scenarios:
Shared Public Terminals : Non-toxic, contact-safe compound supports use in environments where many different people handle the device daily
High-Touch Checkout Counters : Shape-retentive material holds the case's form through months of daily handling without sagging at the corners
Long-Deployment Fleets Across Locations : Anti-aging additives slow visible color shift so replacement cases match existing units over time
