Custom plastic enclosure manufacturing
Custom Plastic Sensor Housings, Built for Your Application
Plasticpartsmfg supports industrial sensor and IoT teams from early prototypes through full-scale production. Develop a housing around your connector interface, PCB cavity, seal groove, threads, mounting features, and transparent windows.
Based in Shenzhen, we help OEM engineering teams balance precise fitment, environmental protection, material performance, and consistent production.
- ±0.05–0.1 mmTypical tolerance range, geometry dependent
- 1–100,000+Production quantities supported
- Prototype to productionMultiple processes for different project stages
Designed around the sensor—not the other way around.
Specify critical interfaces and operating conditions to guide enclosure geometry, material selection, sealing, and assembly.
Manufacturing capabilities
Choose the process that fits your build stage
The right process depends on geometry, material, quantity, and required validation. We support development from precision prototypes through repeatable, high-volume molding.
For functional prototypes and low-volume casting, vacuum casting is suitable for approximately 50–100 units, depending on the project.
Precision CNC machining
A practical choice for high-precision prototypes and small batches, especially when the design includes complex internal geometries, PCB standoffs, or O-ring grooves.
Injection molding
For high-volume production, molding supports consistent wall thickness and material integrity while improving per-unit cost efficiency at scale.
Vacuum casting
Use engineering-grade resins for functional prototypes and low-volume production, with typical project quantities of up to 50–100 units.
Secondary operations and assembly details
Options include ultrasonic welding for hermetic sealing, CNC threading for mounting points, and silk screening for branding or sensor labeling.

Material engineering
Select plastic for real operating conditions
Material choice influences sensor performance, enclosure longevity, and assembly. We help align engineering plastics with mechanical, thermal, chemical, and electrical requirements.
PC (Polycarbonate)
For transparency or high impact strength.
PBT / PPS
For high-temperature stability and electrical insulation in industrial settings.
ABS
A cost-effective option for durable consumer and IoT device enclosures.
PA (Nylon)
Recommended for snap-fit features or applications with high wear requirements.
PEEK / PPSU
For high-performance applications requiring extreme chemical or thermal resistance, or sterilization resistance.
Engineering support
Review the design before production
We review CAD files to identify manufacturing and assembly concerns early, helping reduce costly design iterations and align prototypes with production parts.
Wall thickness consistency
Assess uniform cooling to help prevent warping in injection-molded parts.
Draft angles
Check that parts can be released from molds without damage.
Seal integrity
Confirm groove dimensions are compatible with standard O-ring sizes.
Assembly fitment
Validate tolerance stacks for PCB mounting bosses and connector cutouts.
