1. Material Properties That Affect OEM Manufacturing Decisions
Material physical properties determine core product advantages including wear resistance, portability, user experience, and market positioning. For B2B bulk customization, material characteristics also directly affect production difficulty, yield rate, and subsequent processing schemes.
Durability and Weight Differences
Carbon fiber features ultra-high tensile strength and ultra-light weight, making it the ideal material for slim minimalist wallet designs. Our factory adopts standardized internal layup and curing processes to produce CNC-machined carbon fiber wallets, effectively avoiding fraying, delamination, and structural deformation that plague inferior products. The stable structural strength ensures long-term daily wear resistance without bulging or damage.
Metal wallets adopt aerospace-grade 6061 aluminum and 304 stainless steel materials, with excellent compression resistance and structural stability. The solid metal texture brings a high-end luxury perception favored by high-end consumers and business groups. Compared with carbon fiber, metal wallets have a heavier hand feel, which is precisely the core selling point of premium business EDC accessories.
We support personalized parameter adjustment for OEM projects according to brand positioning: metal wallets can be finely machined into ultra-thin structures to reduce weight, while carbon fiber wallets can be layered and thickened to enhance structural rigidity, fully matching your target audience’s usage preferences.
RFID Blocking Performance – Certified Solutions
Anti-RFID skimming protection has become a standard functional requirement for modern wallets. Both carbon fiber and metal wallets can achieve compliant shielding effects, but the manufacturing principles and processes are completely different.
Carbon fiber itself has conductive properties but cannot form complete signal shielding independently. We embed professional RFID shielding layers in the carbon fiber layup process to achieve stable anti-skimming performance. All products are tested in strict accordance with ISO 14443 and ISO 15693 international standards to ensure effective isolation of mainstream payment and ID card radio frequency signals.
Metal wallets have inherent natural RFID shielding capabilities. Aluminum and stainless steel materials can automatically reflect and absorb radio frequency signals without additional shielding accessories. Our engineering team optimizes structural cutouts while ensuring full shielding to guarantee smooth card access and user operation experience.
We provide complete RFID test reports and compliance certificates for all bulk orders, meeting the market access standards of Europe, North America, Southeast Asia and other global regions, helping B2B buyers eliminate retail shelf and customs clearance risks.
Customization Options for OEM/ODM Projects
Carbon fiber wallets excel in personalized texture customization. Unique woven grain textures, matte/glossy surface treatments, and customized layup sequences can be realized through precise process control. Cooperated with in-house CNC precision cutting, we support custom card slot layout, money clip integration, and multi-functional
key organizer structure design to create differentiated minimalist products.
Metal wallets have richer surface finishing and branding solutions. We provide more than 20 anodized color options, as well as diversified processes such as powder coating, PVD electroplating, wire drawing, and sandblasting. Brand logo, serial number and pattern customization support laser engraving, screen printing and embossing, with no minimum order limit for private label branding.
Relying on a monthly production capacity of over 300,000 units, we support rapid iteration of customized designs.

As a factory with independent CNC production lines, automated assembly workshops and MES intelligent production management system, we realize standardized mass production of carbon fiber and metal wallets.
Minimum Order Quantities for Each Material
Due to the special prepreg layup and curing process of carbon fiber materials, the production process is more sophisticated, with a flexible MOQ of 500–1,000 pieces (adjustable according to design complexity), suitable for brands with mature market positioning and stable order demand.
Metal wallet production lines are highly standardized with mature processes and low trial production costs. The flexible MOQ is as low as 200–300 pieces, which greatly reduces the market trial cost for new brands and start-up sellers. We support small-batch pilot orders and large-scale container orders, realizing flexible scaling from sample verification to mass production.
Tooling and Setup Costs
Carbon fiber wallets require customized molds and vacuum forming equipment for layup and curing, with certain initial tooling investment. Metal wallets mainly rely on CNC fixture customization and die-cast mold development for special-shaped structures.
Our professional engineering team provides free manufacturability evaluation and DFM optimization for all OEM projects, reducing unnecessary tooling and setup costs. For long-term cooperative brand partners, we undertake part of the setup costs and amortize mold fees in bulk orders, effectively reducing customers’ upfront investment pressure.
Turnaround Time for Bulk Orders
Affected by curing and post-processing processes, the standard bulk order cycle for carbon fiber wallets is 25–35 working days. Metal wallets have simpler and more efficient production processes, with a standard delivery cycle of 20–30 working days.
We support urgent order expedited production services. The intelligent scheduling system and 120+ CNC equipment stations ensure stable output of large orders. Even for 50,000+ super large-batch supermarket chain orders, we can prioritize capacity allocation to ensure on-time delivery.
