The wallet has evolved far beyond a simple leather accessory. Today's market demands tech-integrated EDC (Everyday Carry) items that protect RFID signals, survive daily abuse, and make a style statement. For brands and wholesalers planning their next product launch, the manufacturing process you choose—CNC machining or injection molding—will define your product's identity, price point, and market positioning.
Choose wrong, and you face high per-unit costs that kill your margins. Choose wrong, and your "premium" metal wallet cracks under normal use. Choose wrong, and your mass-market plastic wallet fails to justify its shelf price.
At GSTAR, we've spent 13+ years manufacturing both metal and plastic wallets from our factory in China. We operate in-house CNC machining centers alongside injection molding lines, so we don't have a horse in this race—we simply know which process delivers what results. This guide breaks down the technical and commercial differences between CNC wallets and injection molded wallets so you can align your choice with your brand strategy.

Before comparing costs and durability, you need to understand how each product physically comes into existence. Both methods produce wallets, but they start from completely different raw materials and follow opposite manufacturing logic.
CNC (Computer Numerical Control) machining carves a solid block of aluminum, titanium, or stainless steel into a finished wallet. The process removes material—hence "subtractive"—using precision cutting tools controlled by computer programs.
A typical CNC wallet starts as a rectangular billet of aerospace-grade aluminum. Our machining centers then mill away excess material to create the card slots, the outer shell, and any cutouts for quick-access mechanisms. The result is a one-piece construction with no seams, no weak joints, and tolerances measured in thousandths of a millimeter.
Our team operates in-house CNC machining capabilities across our production floor. This vertical integration means we maintain tight tolerances and consistent surface finishes on every metal cardholder and RFID blocking case we produce. We don't outsource this step—our machinists control the entire process from raw billet to finished component.
Injection molding takes the opposite approach. We melt plastic pellets (typically ABS, PC, or nylon blends) and inject the molten material under high pressure into a precision-machined steel mold. Once the plastic cools and solidifies, the mold opens and ejects the finished part.
This is a "formative" process—the material takes the shape of the cavity it fills. Injection molding excels at producing complex geometries: curves, living hinges, snap-fit features, and internal ribs that would be impossible to machine from a solid block.
For clients seeking lightweight, cost-effective solutions, our plastic wallet lines use this method. The upfront tooling investment is significant, but once the mold is approved, each additional unit costs just pennies in raw material.
The material choice drives everything downstream—tactile feel, durability, manufacturing cost, and perceived value.
Metal (CNC): Aluminum and titanium alloys offer a dense, reassuring weight. The surface feels cool to the touch and develops a subtle patina over time. Anodized finishes provide scratch resistance and vibrant color options. Metal wallets signal "premium" in the EDC community—think titanium cardholders retailing at $80–$150.
Polymer (Injection Molding): ABS and polycarbonate plastics are lightweight, flexible, and inexpensive. They can mimic textures like carbon fiber or leather grain through mold texturing. Plastic wallets typically retail at $15–$40 and target mass-market consumers who prioritize affordability over tactile luxury.

Durability is a core selling point for any wallet brand. If you market a "lifetime" product, the manufacturing method must support that claim. We've tested both processes extensively in our factory, and the results are clear.
CNC metal wallets are inherently stronger than their plastic counterparts. A solid aluminum block resists bending, crushing, and impact forces that would shatter injection molded parts. The material density means cards inside stay protected even under significant pressure—say, when someone sits on their back pocket for hours.
The one-piece construction eliminates weak points. There are no glued seams, no ultrasonic welds, no snap-fit joints that could fail. Our metal wallets undergo quality control checks for burrs, edge sharpness, and structural weak points before they leave the factory.
Plastic wallets have a different durability profile. They flex rather than bend permanently—drop a plastic wallet and it bounces; drop a metal wallet and it may dent. However, plastics can crack under extreme cold (below -20°C) or repeated impact at stress points.
We use high-grade polymers that resist UV degradation and maintain structural integrity for years. Our injection molded wallets don't yellow in sunlight or become brittle with age, which protects your brand reputation when customers use the product daily for 3–5 years.
Anodized aluminum resists scratching far better than painted plastic. A CNC wallet's finish wears gracefully—minor scuffs blend into the metal's natural texture. Plastic wallets with painted finishes will show wear at edges and corners within months of daily use.
That said, plastic wallets with molded-in color (not painted) maintain their appearance well. The color runs through the entire material, so scratches don't reveal a different-colored substrate.

For B2B buyers, customization is non-negotiable. Your logo, your dimensions, your unique features—these differentiate your product from competitors. Here's how each manufacturing method handles customization.
CNC is subtractive, which means undercuts and complex internal cavities are difficult or impossible to machine. You can't create a living hinge or a snap-fit latch from a solid block of aluminum. However, CNC excels at sharp angles, chamfers, beveled edges, and sleek, minimalist silhouettes.
We offer Custom Size & Design for CNC wallets. Our engineering team works with your specifications to create a unique profile that stands out in the crowded EDC market. Whether you want a slim 4-card design or a chunky multi-tool wallet, CNC gives you precision that molding cannot match.
Injection molding unlocks design freedom that CNC simply cannot achieve. Curved surfaces, internal ribs, living hinges, snap-fit closures, and complex card retention structures—all possible with a well-designed mold.
The trade-off is the initial tooling investment. A production-grade steel mold for a wallet can cost $5,000–$20,000 depending on complexity. Our engineering team assists with Design for Manufacturing (DFM) to optimize your plastic wallet design for mass production, eliminating common defects like sink marks, weld lines, and warpage before we cut steel.
CNC allows deep logo engraving that won't wear off—we can machine your brand mark directly into the metal surface, creating a permanent, premium look. We can also apply laser etching for finer details or anodized color fills for contrast.
Injection molding allows surface textures like carbon fiber patterns, leather grain, or geometric grip textures molded directly into the part. In-mold labeling (IML) can embed printed graphics permanently into the plastic surface.

This is the most critical commercial factor for wholesalers and online sellers. Let's be transparent about the numbers.
Injection molding requires a high upfront investment for the steel mold (tooling). You pay this cost regardless of how many units you produce. However, once the mold exists, each additional unit costs very little—just the plastic resin, energy, and labor.
CNC has lower upfront costs—no mold to build—but higher per-unit costs due to material waste and machining time. We remove 60–80% of the original aluminum billet to create a wallet, and that scrap represents real cost.
Here's the practical math:
1,000 units: CNC is significantly cheaper. No tooling cost means your total investment stays low.
10,000 units: The break-even point approaches. CNC per-unit cost remains flat, while injection molding per-unit cost drops dramatically once tooling is amortized.
50,000+ units: Injection molding wins decisively. Per-unit cost can drop to $2–$4 for plastic wallets, while CNC metal wallets stay at $8–$15 per unit.
We provide transparent cost breakdowns to help our clients forecast profit margins accurately. When you request a quote, we show you both options side by side—CNC vs. injection molding—with tooling costs, per-unit pricing at various quantities, and recommended MOQs.
CNC lead times are faster initially because there's no mold to build. We can start production within days of design approval. Injection molding requires 15–30 days for mold creation before production begins.
With our 300,000+ monthly production capacity, we ensure that once your mold is approved, we fulfill large bulk orders for supermarkets and top online sellers without delays. Our production planning team coordinates material procurement and machining schedules to hit your launch dates.

Since we specialize in RFID wallets, this comparison is essential. The material choice directly affects how—and whether—your product blocks RFID signals.
Metal wallets naturally block RFID signals. The aluminum or titanium shell acts as a Faraday cage, preventing electromagnetic signals from reaching the cards inside. No additional materials, no extra layers, no added bulk.
This is a massive selling point for security-conscious consumers. You can market a CNC metal wallet as "RFID blocking by design" without any special engineering.
Plastic does not block RFID signals. An injection molded wallet requires an additional RFID-blocking layer—typically a metal mesh or foil insert—placed inside the mold or added as a separate lining during assembly.
We integrate RFID blocking materials seamlessly into our plastic wallets. Our team has developed proprietary methods to embed shielding layers without adding visible bulk or affecting the wallet's flexibility. The result is a plastic wallet that meets RFID blocking standards while maintaining a slim profile.

Modern B2B buyers increasingly evaluate suppliers on environmental practices. Here's how each process compares.
CNC removes material, producing metal shavings as waste. However, aluminum is highly recyclable—we collect our machining scrap and send it to recycling facilities. The energy consumption is significant (machining requires substantial power), but the material waste is fully recoverable.
Injection molding produces minimal material waste—sprues and runners can be reground and reused in production. However, the molds themselves require significant energy to produce (steel machining and heat treatment). The process also consumes energy for melting and injecting plastic.
We manage our machining waste responsibly and optimize our injection molding processes to minimize energy consumption and material waste. Our factory follows lean manufacturing principles to reduce environmental impact across both production lines.

Q: Is a CNC wallet worth the higher price tag?
A: For customers who value durability and premium aesthetics, yes. The material cost is higher, but the product longevity justifies it. A CNC metal wallet can last 10+ years with proper care, while a plastic wallet typically shows wear within 2–3 years. We offer OEM services to help you position this value proposition to your end-users through packaging, marketing copy, and product storytelling.
Q: Can you add an RFID blocking feature to an injection molded wallet?
A: Absolutely. At GSTAR, we insert RFID shielding materials during the molding process or via a separate lining during assembly. Our team ensures full 360-degree protection that meets industry testing standards. We've developed methods to embed the shielding without adding visible bulk or compromising the wallet's flexibility.
Q: What is the typical MOQ difference between CNC and injection molding?
A: CNC allows much lower MOQs—we can produce as few as 100–200 units because there's no mold cost to amortize. Injection molding requires higher MOQs (typically 1,000+ units) to justify the tooling investment. We provide flexible MOQ options to accommodate both startup brands testing the market and established companies running large production cycles.
Q: Which process is better for a custom logo?
A: For a permanent, high-end look, CNC engraving is superior—we machine your logo directly into the metal surface, and it won't wear off with daily use. For a colored or embossed logo on plastic, injection molding is better—we can texture the logo into the mold or use in-mold labeling for printed graphics. We can also combine processes for a hybrid approach, such as a plastic wallet with a CNC-machined metal badge.
Q: Can GSTAR help me design a product that uses both metal and plastic?
A: Yes, we regularly work on hybrid designs—for example, a plastic core with a metal frame, or a CNC-machined front plate with an injection molded back. Our engineering team provides OEM & ODM solutions to merge these materials effectively, ensuring proper fit, finish, and durability. We handle the complexity of multi-material assembly in-house.
Q: How long does a typical OEM project take from concept to delivery?
A: For CNC wallets, we can move from design approval to production within 7–15 days. For injection molded wallets, add 15–30 days for mold creation. Total timeline depends on design complexity, finishing requirements, and order quantity. Contact our team with your project details, and we'll provide a precise timeline with milestones.
Q: What finishing options do you offer for metal wallets?
A: We offer anodized finishes in a wide range of colors (black, silver, gunmetal, gold, rose gold, blue, red), brushed or polished surfaces, sandblasted textures, and laser-engraved logos. Our in-house finishing capabilities ensure consistent quality across your entire order.
