Models and Options
Available in standard wall thicknesses (2.0–4.0 mm) with customizable features:
- Molded-in color options (black, gray, beige, custom RAL)
- Textured surfaces (leather, grain, matte)
- Metal insert integration for mounting points
Materials and Structure
Material: PC+ABS blend offers excellent impact resistance at low temperatures and good heat resistance. UV stabilizers prevent yellowing over the vehicle lifetime. Compliant with EU RoHS directive.
Structure: Designed with uniform wall thickness to avoid sink marks. Ribs and bosses are strategically placed for assembly strength without adding weight. Slides and lifters in the mold accommodate undercuts for snap-fit features.
Applications
- Instrument panel trim and bezels
- Door inner handle surrounds
- Center console storage bins and lids
- Air vent louver components
- Interior lighting diffusers
Customization
We tailor each project to your requirements:
- DFM analysis to optimize part design for tooling and production
- Prototype development using low-cost rapid tooling or 3D printing
- Material selection support (e.g., PC/ABS with different FR ratings, ASA for weatherability)
- Secondary operations: ultrasonic welding, heat staking, clip attachment
Case Study
Client: Tier 1 automotive interior supplier
Application: Center console trim with integrated snap-fits and hidden clip channels
Challenge: Required invisible assembly lines, tight tolerances for flush fit with surrounding panels, and high surface quality without blemishes.
Solution: DTG performed mold flow analysis to optimize gate location and cooling, achieving uniform fill. Slide actions created undercuts for snap-in features. First article inspection confirmed dimensional compliance.
Result: Mass production of 20,000 units per month with 99.5% yield. Customer's assembly line reported zero fit issues.
FAQ
What is the typical lead time for interior trim tooling?
Tool fabrication takes 30–40 days for medium-complexity parts. Samples delivered within 7 days after tool completion.
Can you achieve a leather-like texture on the surface?
Yes. We can apply EDM texture or chemical etching to produce fine leather, grain, or stippled patterns as per your sample.
How do you prevent sink marks on thick sections?
We optimize rib-to-wall thickness ratios and use conformal cooling in the mold. Our DFM analysis identifies potential sink areas and adjusts design accordingly.
Do you offer color matching services?
Yes. We can match any RAL, Pantone, or OEM color using masterbatch. We also offer UV-stable formulations for interior parts.
What quality inspections are performed?
In-process (dimensional, visual), first article inspection (FAI) with CMM, and final random sampling per AQL 2.5 standard.
Can you handle low-volume production (under 1000 units)?
Yes. We accept low-volume orders using prototype or bridge tooling. MOQ starts from 500 units for PC+ABS parts.
What are your payment terms?
Typically 50% deposit with order, 50% before shipment. Negotiable for long-term contracts.
How do you ensure confidentiality of our design?
We sign a non-disclosure agreement (NDA) before project start. All files are stored securely and not shared without permission.
