OEM Custom OEM POS Terminal Housing - Precision ABS Shell & Silicone Keypad Assembly from China Suppliers and Factory Manufacturer, Product
Product Description
Product Overview
This premium POS terminal enclosure is a comprehensive hardware solution featuring a high-impact ABS plastic shell integrated with a tactile silicone button plate. Engineered for durability and ergonomic performance, this assembly is designed for modern payment terminals, handheld scanners, and industrial control devices. At Shenzhen Sunmy Hardware, we provide a full-spectrum service from initial DFM (Design for Manufacturing) to final mass production, ensuring every component meets the rigorous demands of the global financial and retail sectors.
Process & Manufacturing Insights
Our production utilizes advanced Plastic Injection Molding technology to achieve the complex internal geometries required for electronic component mounting.
Precision Tooling
We utilize high-grade steel molds (NAK80 or S136) to ensure consistent dimensions over long production cycles.
Material Science
The outer shell uses premium ABS or PC-ABS blends for superior flame retardancy (UL94-V0) and impact resistance.
Secondary Processing
For the button plate, we employ Silicone Compression Molding with optional screen printing or laser etching for permanent character durability.
Integrated Assembly
Our facility supports ultrasonic welding and insert molding to ensure a seamless fit between the plastic housing and electronic interfaces.

Technical FAQ
Please provide 2D drawings (PDF/DWG) and 3D models (STEP/IGES/STP). If you only have a prototype or an idea, our development team can assist in creating the necessary CAD files for production.
Typically, mold design and fabrication take 25–35 days. Once the T1 samples are approved, mass production usually requires 15–20 days depending on the order volume.
Yes. We offer full assembly services, including the integration of silicone keypads, plastic windows (PMMA/PC), and metal inserts, delivering a "ready-to-install" housing to your assembly line.
Our standard MOQ for mass production is 1,000 sets. However, we support lower quantities for initial market testing and pilot runs following the mold validation phase.

Frequently Asked Questions
What materials are best suited for a POS terminal housing in high-humidity environments?
For high-humidity or outdoor environments, we recommend PC-ABS blends with UV-stabilized additives and a hydrophobic surface coating. These materials offer superior moisture resistance while maintaining structural rigidity and flame retardancy to UL94-V0 standards.
Can the silicone keypad be customized with backlit or color-coded buttons?
Yes. We support translucent silicone with laser-etched characters for LED backlighting compatibility, as well as multi-color keypads using two-shot compression molding. Custom Pantone color matching is available for all button zones.
What surface finish options are available for the ABS plastic shell?
We offer a wide range of surface finishes including MT-standard textures (matte, leather grain, fine grain), high-gloss polish, soft-touch rubber coating, and UV-resistant clear coating. Custom textures can also be applied directly to the mold surface for zero additional cost at scale.
How do you ensure dimensional accuracy across large production batches?
Our quality control process includes First Article Inspection (FAI) using CMM (Coordinate Measuring Machine) equipment, in-process sampling at defined intervals, and final outgoing inspection. All critical dimensions are controlled to ±0.05mm–±0.1mm tolerance, with full traceability documentation provided per batch.
Is it possible to add EMI shielding or metal inserts to the plastic housing?
Absolutely. We support insert molding for brass or stainless steel threaded inserts, as well as conductive coatings (copper or nickel spray) applied to interior surfaces for EMI/RFI shielding. These options are fully compatible with our standard injection molding workflow.
What certifications can Sunmy support for products entering the European or North American market?
We can supply components and assemblies with RoHS and REACH compliance documentation as standard. UL94-V0 flame retardancy certification is available for applicable materials. For market-specific requirements such as CE or FCC, we work closely with third-party testing labs to support your certification process.
