China Custom Medical Device Housing: Leading China Suppliers and Factory for High-Quality Solutions Manufacturers, Products
Product Description
Product Overview
This high-precision housing is designed for a handheld medical diagnostic device. Manufactured from medical-grade ABS, it meets strict cosmetic and dimensional standards required by the healthcare industry. As an OEM partner, Sunmy Hardware understands that medical products require not just functionality, but also a pristine, easy-to-clean surface finish that resists sterilization chemicals.
Manufacturing Process Insight
Scientific Molding
We utilize scientific molding principles to optimize the injection speed, pressure, and temperature. This ensures the part is filled consistently without "short shots" or internal stress.
Cosmetic Control
To achieve the smooth matte finish, the mold cavity was textured (VDI 3400 standard). We placed gate locations strategically in non-visible areas to ensure the exterior appearance is flawless.
Clean Production
Produced in a controlled environment to minimize dust and contamination, essential for medical components.
Key Features & Benefits
Material Compliance
Molded using biocompatible ABS resin that meets UL94-V0 flammability standards.
Snap-Fit Design
Features complex internal undercuts and snap-fits for screw-less assembly, reducing final assembly time.
Aesthetic Quality
Zero sink marks or flow lines on the A-side (visible surface), even opposite to internal ribs.
Durability
High impact resistance to withstand drops in a hospital environment.
Technical FAQ
› Q1: What surface finishes can you provide for injection molding?
A1: We offer everything from high-gloss polishing (SPI-A1) to various EDM textures (VDI standard) and Mold-Tech textures.
› Q2: Can you help with DFM (Design for Manufacturability)?
A: Yes, we provide a detailed DFM report to analyze draft angles, wall thickness, and potential sink marks before cutting steel.
› Q3: What is the lead time for T1 samples?
A3: Typically 25–35 days for mold fabrication and first sample delivery, depending on mold complexity.

Frequently Asked Questions
-
Q What materials are suitable for medical device injection molding?
Medical-grade ABS, PC, PP, and PEEK are commonly used. These materials offer biocompatibility, chemical resistance, and the ability to withstand sterilization processes including autoclaving and chemical disinfection. Material selection depends on the application's regulatory and performance requirements.
-
Q What surface finish options are available for injection-molded medical housings?
We offer a full range of finishes — from high-gloss mirror polish (SPI-A1) to fine matte textures (VDI 3400 / Mold-Tech standards). For medical devices, a matte or semi-gloss finish is often preferred as it hides fingerprints and is easier to clean.
-
Q How do you ensure dimensional accuracy and part consistency across production runs?
We apply scientific molding methodology — systematically documenting and validating optimal injection parameters (speed, pressure, temperature, cooling time). Each production run follows a controlled process sheet, and parts are measured using CMM and optical comparators to verify critical dimensions.
-
Q Can you support low-volume and high-volume production for medical components?
Yes. We support prototype runs, low-volume NPI (New Product Introduction) batches, and high-volume mass production. Our tooling and process validation approach scales accordingly, with full documentation available to support regulatory submissions such as FDA 510(k) or CE marking.
-
Q What quality certifications and standards does your facility comply with?
Our manufacturing facility operates under ISO 9001 quality management standards. For medical-grade components, we follow strict cosmetic inspection criteria, material traceability requirements, and controlled production environments to minimize contamination risks.
-
Q What information do I need to provide to get a quote for a custom injection-molded housing?
Please share your 3D CAD files (STEP or IGES preferred), 2D drawings with tolerances, material requirements, annual quantity estimates, and any surface finish or regulatory specifications. Our engineering team will review your files and provide a detailed DFM report along with a technical quotation.
