OEM/ODM customization capability - integrating products into your brand and system
Our customized services cover four major dimensions
• Customized specifications: Volume, diameter, height, valve opening type - within the safety standard range, adjust as needed
• Customized appearance: Bottle body color, shoulder color matching, enterprise LOGO, product label - Let the gas cylinder become your mobile billboard
• Customized identification: Laser engraving, screen printing, permanent coding - achieving full life cycle traceability management
• Customized packaging: Exclusive packaging solutions, pallet specifications, and shipping mark designs - tailored to your warehousing and logistics systems
From sample confirmation to batch delivery, we offer one-on-one dedicated account manager coordination to ensure that every customized detail is precisely implemented.
Scene One: Metal Fabrication & Welding Workshops
Traditional steel CO2 tanks are heavy and bulky, occupying large storage space inside compact welding workshops. Frequent tank transportation and replacement add extra labor burden to workshop staff. Steel tanks are prone to internal rust, which generates impurities that create welding pores and oxidation defects once gas supply is unstable. Mixed tank specifications also lead to messy inventory counting across multiple production lines. Midstar aluminum CO2 welding cylinder adopts aviation-grade aluminum material, cutting total weight by 30% so a single worker can move and replace tanks effortlessly. Its smooth, rust-free inner wall ensures pure CO2 shielding gas, effectively improving welding surface quality. Unified standard sizes and universal valve interfaces simplify cross-workshop stock management and avoid mismatches with mainstream welding regulators.
Scene Two: Industrial Gas & Welding Equipment Distributors
Generic steel CO2 cylinders have inconsistent thread standards, resulting in high after-sales return rates caused by incompatible valves and supporting accessories. Scattered small retail orders greatly compress profit margins, while blank unbranded tanks cannot help distributors launch exclusive customized product lines for group manufacturing clients. Our aluminum CO2 cylinder fully meets ISO 7866 and DOT-3AL international standards, with complete certification documents to speed up full-container customs clearance for global export orders. We provide full OEM customization including tank color, laser-engraved enterprise logos and matched trolley & regulator packaging kits, guiding wholesalers to focus on large-volume bulk orders from factory groups instead of fragmented individual small orders.
Scene Three: Automotive & Precision Processing Plants
Heavy steel CO2 tanks are difficult to transfer between automated welding stations and cutting lines. Without exclusive identification marks, cylinders get mixed up and lost easily in multi-branch factories, increasing regular inspection workloads. Rust residues inside ordinary steel tanks may pollute precision automotive parts and thin metal workpieces during welding. Midstar lightweight aluminum tank features clean internal treatment without particulate contamination, fully meeting the strict production standards of automotive frames and precision metal parts. Custom engraved logos support full lifecycle asset tracking across factory branches, and the leak-proof valve structure reduces daily maintenance difficulty for facility managers without professional gas operation training.
Full-process support from concept to mass production: From drawing review, prototype making to mass production and quality inspection, we offer one-stop services, significantly shortening your product launch cycle.
Flexible cooperation based on demand: Whether it's a small-batch trial order or a long-term large-scale framework purchase, we can offer competitive tiered pricing and stable inventory planning.
Cross-industry application expert: Our gas cylinder solutions have been successfully applied in fire-fighting equipment, medical devices, diving equipment and the beverage industry. We are glad to apply our cross-industry experience to solve your specific challenges.
Regarding packaging
In order to deliver our products to you in the condition in which they were sent, we use strict, strong, efficient and environmentally friendly packaging methods.
Our standard packaging method for our products is to cover them with plastic bags, put them into cartons, then place the cartons on pallets and wrap them tightly with stretch film to ensure that the cylinders do not collide with each other during transportation. Other packaging methods can be provided upon request.

FAQs
Q: Can you create our design?
A: Of course, your custom design (ODM) is welcome.
Q: Can I get samples?
A: It depends on what kind of product you need. For small products, we can provide you with samples. However, for large products, we do not recommend to provide samples because of the complicated shipping process and high shipping cost. However, we can provide you with COA and quality related certificates for better quality assurance.
Q: Can I purchase your cylinders at retail?
A: Mid-Star Gasoline Cylinders are not available for purchase at retail and cannot be sold to individuals. Only business orders will be accepted.
