Custom Injection Molded Plastic Enclosures
Pre-Drilled & Tapped Holes for Connectors, Displays, and Controls
Precision-engineered thermoplastic enclosures manufactured with customer-specific hole patterns, threads, and cutouts for rapid integration of electronic components. Eliminate secondary machining operations and reduce assembly costs by 40-60%.
Engineering & Economic Advantages
Eliminate Secondary Machining
Holes are molded-in with precise location, diameter, and thread specification. No post-molding drilling, tapping, or CNC operations required.
Reduce Assembly Costs 40-60%
Direct component mounting reduces labor, eliminates machining fixtures, and decreases assembly errors. Typical ROI within first production run.
Superior Dimensional Consistency
Molded-in features maintain ±0.15mm tolerance across thousands of parts. Superior to post-machining which introduces variability.
Design Integration Process
Step 1: Component Layout Analysis
Our engineers analyze your PCB layout, connectors, displays, buttons, and cooling requirements to determine optimal hole placement, spacing, and wall thickness.
Step 2: DFM Review & Simulation
Design for Manufacturability (DFM) report includes mold flow analysis, stress points, and draft angle verification to ensure high yield and quality.
Step 3: Prototype Validation
3D-printed or rapid injection molded prototypes provided for physical fit-check with your components before production tooling.
Step 4: Production & Quality Assurance
Statistical process control (SPC) monitors critical dimensions. First article inspection reports include CMM data for all pre-drilled features.
Common Pre-Drilled Features
- DB9, DB25, USB, HDMI, Ethernet ports
- 7-segment, LCD, TFT, OLED display cutouts
- Tactile buttons, membrane switch openings
- BNC, SMA, RF connector mounts
- Cooling fan mounts with screw posts
- Strain relief grooves for cables
Cost-Benefit Analysis: Molded-in vs. Post-Machined Holes
| Factor | Custom Pre-Drilled Enclosure | Standard Enclosure + Post-Machining |
|---|---|---|
| Per-Unit Cost Impact | Minimal increase (5-15%) for molded-in features. No additional machining cost per piece. | Significant added cost (25-60%) for CNC drilling/tapping, fixturing, and secondary handling. |
| Lead Time | 15-30 days after design approval. Features created during primary molding cycle. | Additional 5-15 days for secondary operations, plus scheduling delays. |
| Dimensional Consistency | ±0.15mm tolerance maintained across entire production run via mold precision. | ±0.25-0.5mm tolerance typical; variability from fixturing, tool wear, and operator error. |
| Assembly Labor | Reduced 40-60% – components mount directly into prepared holes/threads. | Additional alignment steps required; potential for cross-threading or misalignment. |
| Design Flexibility | High – complex shapes, undercuts, and multi-level holes possible in mold design. | Limited by drill bit geometry and CNC access; additional setups increase cost. |
