Automotive Plastic Injection Molding: Precision & Aesthetics

Expertise in Small Automotive Technical Parts

In modern automotive engineering, reliability is found in the details. Moving away from the race for size, we specialize in the injection molding of **precision components, connectors, and functional supports**.

Our infrastructure is scaled to produce small to medium-sized parts (from a few millimeters up to 20-30 cm), where tolerances are measured in hundredths and material quality is critical for the safety and durability of on-board systems.

1. Geometric Precision and Dimensional Control

For parts such as LCD screen brackets, sensor housings, or locking elements, there is no room for error. Our expertise focuses on strict adherence to the 3D file (“3D Data takes precedence”) and associated 2D drawings.

We guarantee compliance on critical points:

Functional Dimensions (Key Inspection Dimensions): We monitor through metrology the dimensions marked as critical (e.g., mounting centers, 5.5mm or 12.0mm bores) to ensure perfect assembly on your production lines.
Detail Finesse: Our molds are machined to reproduce tiny radii (General Radii 0.2mm) and complex geometries without deformation.
Flash-free production: On small electronic parts, a flash can cause a short circuit or an aesthetic defect. We guarantee parts that are “Clean and free from flash” straight from the press.

2. Material Integrity for Severe Applications

Small technical parts under the hood or behind the dashboard undergo intense thermal and vibratory stress. Unlike basic aesthetic parts, these functional components require an intact molecular structure.

Exclusive Virgin Material: To guarantee mechanical properties (impact resistance, clip elasticity), we strictly respect “No Regrind Material” requirements (no re-injected reground material) when the specifications demand it.
Technical Polymers: We regularly process high-performance materials (filled PA6.6, PBT, POM, ABS/PC) for parts that must resist automotive fluids and temperature variations.

3. Our Typical Automotive Applications

We do not manufacture interior trim or large body panels. Our core expertise is focused on the "invisible" yet indispensable elements:

On-board Electronics: PCB holders, LCD frames and brackets, protective housings.
Connectors and Fasteners: Clips, fasteners, cable guides, fluid connectors.
Mechanisms: Plastic gears, axles, levers, and kinematic components for air vents or seat controls.

4. A Quality Process Adapted to Small Batches and OEM Standards

The production of small parts requires specific rigor. A drift of just a few microns in a multi-cavity mold can make an entire batch unusable.

We apply industry validation methods (PPAP / IS):

Dimensional validation of every mold cavity.
100% visual inspection or statistical control according to AQL to detect voids or surface defects.
Compliance with environmental directives (RoHS) for all electronic components.
