EV充電器OEMガイド：カスタム金型とCMFデザイン

Working with a private label ev charger manufacturer is the one decision that separates a commoditized product from a brand with defensible market share. When every charger on the market is a generic black box, you are forced to compete on price alone, which inevitably leads to margin compression and a diluted brand identity.

This guide serves as a practical manufacturing brief, focusing on the core customization questions that determine brand value. We cover the technical process for CMF design, from matching specific finishes like “Tesla Silver” to customizing LED breathing light patterns. We also break down the costs and engineering limits for mold modifications like logo embossing and the logistics of creating drop-test certified packaging for Amazon FBA.

CMF Design: Can We Match the “Tesla Silver” or “Matte Black” Finish?

Matching a factory automotive finish isn’t about finding the right paint; it’s about simulating a complex, multi-layer industrial process on materials that can’t withstand automotive-grade oven curing.

Replicating Factory Automotive Finishes on Accessories

While an exact 1:1 match to a vehicle’s multi-layered, oven-cured paint is not feasible for accessories, KelyLands can simulate these premium aesthetics. We use specialized CMF (Color, Material, Finish) processes on high-strength ABS and PC plastics to create a look that complements modern EV designs. The core difference lies in the industrial process itself.

• Automotive paint involves complex, high-temperature robotic application, a process fundamentally different from what’s used for consumer electronics.
• We achieve similar visual depth and quality using methods like dual-layer spray coating, protective UV finishing, and color-matched masterbatches mixed directly into the polymer.
• To ensure perfect alignment with your brand standards, we develop custom CMF physical samples for your approval before starting mass production.

Achieving a “Matte Black” Aesthetic with Plastic Injection Molding

We offer two primary methods to create a durable and consistent matte black finish. The first and most resilient option is mold texturing, where a matte surface is etched directly into the steel injection mold. This makes the finish an integral part of the plastic housing, completely resistant to wear, scratches, or peeling. For a different tactile feel, we can apply a soft-touch rubberized paint or a flat matte coating after the part is molded. This second method provides a more premium, velvety feel. Achieving custom colors for housings and cables, including specific matte shades, typically requires a Minimum Order Quantity (MOQ) of 500 units.

Pantone Matching for “Tesla Silver” and Custom Colors

We can precisely match specific brand colors, including complex shades like “Tesla Silver,” by using the Pantone Matching System. You provide the Pantone code, and our engineers create a custom-colored masterbatch for injection molding. This ensures absolute brand consistency across your entire product line. Our process supports a wide range of polymers like ABS, PC, PP, and the TPU used for our flexible cables. We can also produce finishes with metallic flakes or pearlescent effects to simulate an automotive-grade metallic appearance. Before starting mass production, we provide physical color chip samples to guarantee the final shade meets your exact specifications.

LED Logic: Can You Customize the Breathing Light Patterns?

Yes, LED breathing light patterns are fully customizable, but the method depends on the underlying circuit. Analog systems offer simple frequency adjustments by changing physical components, while digital microcontroller systems provide complete programmable control over brightness, speed, and complex patterns.

Analog Circuit Customization

For analog-based breathing lights, customization is a hardware-level adjustment. The effect is typically driven by an operational amplifier circuit where the values of specific resistors and capacitors in the feedback network dictate the breathing frequency and feel. Changing these component values allows you to modify the oscillation speed. While this approach is simple, compact, and cost-effective, its flexibility is limited to what’s physically soldered onto the PCB. You can add a rotary potentiometer to give the end-user real-time control over the speed, but the fundamental pattern remains fixed.

Digital and Microcontroller Customization

Using a microcontroller with pulse-width modulation (PWM) unlocks extensive, software-defined control over the LED. This method allows for precise and programmable adjustments to nearly every aspect of the breathing effect, making it ideal for OEM clients who want a unique visual identity for their products. Instead of changing hardware, you modify firmware to achieve the desired result.

• Adjust the brightness range to create effects from “heavy breathing” (high peak brightness) to “soft breathing” (low peak brightness).
• Implement smooth dimming transitions with adjustable fade rates and unique non-linear patterns.
• Manage independent breathing patterns across multiple LEDs using dedicated driver ICs for complex status indicators.
• Utilize pre-built software libraries to deploy various effects like heartbeat, strobe, or custom sequences beyond simple fading.

Mold Modification: What Is the Cost to Emboss My Logo in Plastic?

Embossing your logo directly into the plastic housing is a permanent branding solution defined by a one-time tooling fee, a standard MOQ, and a clear production timeline, making it highly cost-effective at scale.

Adding a custom embossed logo is a straightforward process for private label orders. It provides a premium, durable branding feature that won’t peel or fade over the product’s lifetime. The primary investment is in modifying the injection mold, which then allows your logo to be seamlessly integrated into every unit produced.

Initial Tooling and Mold Fees

The main investment for embossing a logo is the one-time fee for mold modification. This payment covers creating the custom tooling needed to press your brand’s signature directly onto the product’s plastic housing. Standard tooling costs for a logo typically range from $300 to $1,000 USD. This is a single charge for each unique logo design. We use durable steel and aluminum molds to guarantee high precision and long-term use across thousands of production runs.

Minimum Order Quantity (MOQ) Requirements

Custom molding is an efficient process that requires a minimum production volume to be viable. This volume spreads the initial tooling investment out, making the per-unit cost competitive. The standard MOQ for products with an embossed logo starts at 3,000 units. After paying the one-time tooling fee, the per-unit production cost is nearly identical to a non-customized product. Embossing is particularly cost-effective for clients with annual orders between 50,000 and 100,000 units.

Production Timeline and Process

The complete timeline for adding an embossed logo involves design confirmation, mold fabrication, and the start of mass production. The entire process, from your design approval to the first full production run, takes approximately 52 to 75 days. This period includes creating the physical mold, producing initial samples for you to approve, and then launching full-scale manufacturing. Our team coordinates each step to maintain a clear and predictable schedule.

Technical Specifications and Design Limits

Embossing delivers a permanent, high-end branding solution. To ensure logo clarity and the structural integrity of the product housing, we follow a few key design constraints. The depth of the logo relief is limited to a range of 0.3mm to 0.8mm. This specific depth prevents the plastic from weakening or failing while keeping the logo sharp and visible. We use stamping techniques for flat surfaces and hydroforming for curved components to achieve the best possible finish for your design.

Packaging: Is the Box Drop-Test Certified for Amazon FBA?

Yes, our packaging is engineered to meet Amazon’s current ISTA 6-Amazon standards, ensuring your products arrive at fulfillment centers undamaged and ready for processing without delays or penalties.
