Custom Powder Coating Solutions for Every Product
First, alkaline cleaning and phosphating are performed to remove oil stains and impurities from the blank surface. Once the stainless steel cup shell is grounded, electrostatically charged powder particles are sprayed onto it. The powder-coated cup is transferred to a curing oven maintained at 180–200°C. We offer a range of surface finishes: high-gloss, matte, metallic, and gradient, plus special textures like crackle and snowflake.
We use a polyester or epoxy-polyester hybrid resin system to make textured powder coating. It creates a controllable rough surface for better grip and anti-slip performance. The cured coating forms a strong protective film, which is impact-resistant and abrasion-resistant. Compared with much thinner liquid paint, powder coating can form a thicker and more resilient protective layer, which plays a buffering role when the cup falls.
The coating of pet food bowls must meet the safety standards for direct contact with food and drinking water. The powder coating adopts a food-grade formula and does not contain BPA, phthalate esters, and other harmful substances. After the high-temperature curing process, the coating is fully crosslinked, and residual monomers and volatile substances are completely eliminated. The formed surface is compact, non-porous, and easy to clean.
Compared with spray painting, powder coating offers better resistance to spirits such as gin and whisky, and inferior coatings are easily damaged by these beverages. The cured powder coating film features chemically inert properties and will not react with botanical oils in spirits. Hip flasks with conventional coatings are prone to flavor transfer, while the powder coating process prevents changes to the liquor’s taste.
The powder coating layer, paired with the vacuum insulation structure, can avoid water droplet condensation on the exterior of the growler and prevent hands from getting wet when holding it. The textured coating delivers reliable grip, and the growler filled with liquor is more stable to lift and not easy to slip. Our powder coating finish is durable and can withstand daily repeated use. Even if it is frequently carried back and forth to breweries and party occasions, the growler’s appearance can still be kept intact.
The coating used on metal coolers and large-capacity jugs must be able to withstand harsh outdoor environments. The powder coating used for these products adopts UV-stable formulations, which do not easily fade or chalk after prolonged sun exposure. The coating can also form a protective barrier to isolate water vapor and oxygen and prevent metal corrosion. For stainless steel vacuum jugs and metal cooler shells used in outdoor scenarios such as camping, the powder-coated surface can be gripped more stably even if gloves are worn.
Can coolers can also deliver protective effects and functional performance with the help of powder coating. The high-performance powder coating creates a scratch-resistant surface and can also be put into a dishwasher for cleaning. The finish will not get damaged even after repeated cleaning. The coating can also bring a non-slip grip, making the cooler easier to hold even when condensation forms. Powder coating can be combined with laser engraving for slim can coolers suitable for standard 12 oz cans. The engraved brand logo has a crisp outline and is durable.
Powder Coating Quality Control Process That Guarantees Mass Production
We help you avoid the risk of “great samples, bad bulk orders.” Powder coating is not a simple one-step process but a multi-stage process including chemical reaction and high-temperature treatment, and every parameter will affect the final quality. We strictly implement the four-step powder coating quality inspection process, from raw material inspection to final packaging, to ensure your customized project will not go wrong. Each process is closely monitored by our dedicated quality inspection team; each batch of products can be traced back, with the corresponding powder batch number, curing temperature curve, and operator ID available for reference.
| Process Name | What We Do | Your Benefit |
|---|---|---|
| Color Matching & Powder Sampling | We match your Pantone color using our in-house powder library, apply the coating under the same parameters as mass production, and send physical samples for your approval. We also provide texture samples including matte, glossy, sandy, and hammer tone. Each sample is labeled with its powder lot number and curing profile. | Zero Guesswork. You see and feel the exact powder-coated finish before committing to mass production. |
| Metal Pre-Treatment | Chemical cleaning, alkaline degreasing, and phosphating to remove oils, grease, and oxidation from the metal surface. This step creates a conversion coating that dramatically improves powder adhesion. | Maximum Adhesion. Proper pre-treatment is the single most important factor in preventing peeling and flaking. It ensures your powder coating survives years of use. |
| Electrostatic Spraying & High-Temperature Curing | Electrostatic spray guns apply positively charged powder particles to the grounded metal substrate. The coated product then enters a curing oven at 180–200°C, where the powder melts, flows, and chemically cross-links into a hard film typically 60–100 microns thick. | Consistent Thickness. Every unit receives the same uniform coverage and curing profile, eliminating human error and ensuring batch-to-batch consistency. |
| Strict Powder Coating QC Testing | We perform cross-hatch adhesion testing (ASTM D3359), salt spray testing (ASTM B117), and dishwasher safety testing on every production batch. Additional tests include impact resistance and color difference measurement (ΔE < 1.5). | Peace of Mind. Verified powder coating durability and food safety for your target market, with test reports available upon request. |
