Custom Design Two-Color Turn Signal Mold: Product Introduction
Product Overview
Our custom-designed Two-Color Turn Signal Mold represents a breakthrough in automotive lighting precision and efficiency. Engineered for superior performance, this mold enables the simultaneous injection molding of two distinct plastic materials or colors in a single, integrated cycle. The result is a seamless, high-strength turn signal lens with clear and amber sections, eliminating the need for secondary assembly, painting, or bonding processes. This innovative approach ensures perfect registration between colors, exceptional aesthetic quality, and enhanced product durability against moisture ingress and environmental stress.
Manufacturer Advantages
Integrated Expertise
We are a specialized manufacturer with core competencies in both precision mold manufacturing and injection molding processes. This vertical integration ensures flawless design-for-manufacturability, superior mold quality, and optimal production outcomes.
Cost-Effectiveness
While the initial tooling investment is tailored to your design, our process significantly reduces total part cost by combining two manufacturing steps into one, minimizing labor, scrap rates, and supply chain complexity.
Advanced Engineering & Technology
Our facility utilizes state-of-the-art CAD/CAE software for mold flow analysis and structural simulation, guaranteeing optimal gating, cooling, and part performance. We employ high-precision CNC machining, EDM, and dedicated two-shot/overmolding presses to achieve micron-level accuracy.
Proven Project Management
From initial concept to final mass production, we provide a streamlined, collaborative customization process. Our team of experienced engineers works closely with clients to refine designs, select optimal materials (compatible PC, PMMA, etc.), and deliver prototypes for rapid validation.


Certifications and Qualifications
Our commitment to quality and international standards is demonstrated through our certifications, which include (but are not limited to):
- IATF 16949: 2016 certification for automotive quality management systems, ensuring compliance with the strictest global automotive industry requirements.
- ISO 9001: 2015 certification for our quality management processes.
- ISO 14001 certification for environmental management.
Our molds and production processes are capable of delivering parts that meet relevant automotive lighting standards such as SAE, ECE, and GB regulations for turn signal function, color, and durability.



Frequently Asked Questions (FAQ)
Q1: What are the key design considerations for a two-color turn signal mold?
A: Critical factors include the parting line location, material compatibility (adhesion between substrates), shut-off design for color separation, wall thickness uniformity, and gate placement. Our engineering team will provide detailed Design for Manufacturability (DFM) feedback.
Q2: What is the typical lead time for mold development and sampling?
A: Lead time varies based on mold complexity. Typically, a standard two-color mold takes approximately 10-14 weeks from design approval to first article samples. Prototype/pre-production samples can often be delivered sooner using soft tooling or dedicated methods.
Q3: Can you work with our provided 3D part data?
A: Absolutely. We can initiate the mold design based on your finalized 3D data (e.g., STEP, IGES formats). We highly recommend an early design consultation to ensure optimal manufacturability and cost-efficiency.
Q4: What materials are commonly used for two-color turn signals?
A: The most common combinations involve Polycarbonate (PC) for its impact strength and PMMA (Acrylic) for superior clarity and UV resistance. We assist in selecting the perfect material pair for your performance and regulatory requirements.
Q5: How do you ensure consistent color separation and part quality?
A: This is ensured through precise mold machining, robust core-back or rotary plate mechanisms, rigorous process parameter control during molding, and a comprehensive First Article Inspection (FAI) and Production Part Approval Process (PPAP) protocol.
Q6: What is your minimum order quantity (MOQ) for production parts?
A: Our MOQ is flexible. While we accommodate prototype and low-volume requests, we are optimized for high-volume automotive production, offering scalable and cost-competitive rates for large-scale orders.
