A good coating for your barrel mold can help you extend the life of your mold and provide better protection against corrosion. It also helps improve the lubricity of the mold, making it easier to fill. It can also help reduce the coefficient of friction, thereby helping to improve the efficiency of the production process.

Coating the bucket mold with a chemical solution will help increase its durability and corrosion resistance. The process involves dipping the mold in a chemical solution, then dipping it again to achieve a smooth surface finish. It is also possible to coat the mold with metal. However, this process can be expensive. It is important to understand the differences between coatings before deciding which type to use.

Hard chrome coating is a protective coating that can be applied to molds. It is used at a low temperature of 130 F. This is a safe way to protect the mold. It provides the best surface finish. It also provides wear protection. It offers hardness up to 20 RC points, which is much harder than the base steel. This coating is also used to help unscrew the core of the bottle cap. It also helps protect textured surfaces and maximize release. In addition, it helps to protect the thermal conductivity of the mold. Another coating that can be applied to barrel molds is a nickel-cobalt alloy coating. Ideal for deep ribs, this coating also provides corrosion protection. The coating has a coefficient of friction of 0.10 against steel. It also increases resin flow by 4% to 8%.

Nibore is another coating used to help with sticky polymers. The coating is applied without the use of an anode. This is an autocatalytic process, which means it does not affect the thermal conductivity of the mold. This coating is used on plastic molds with textured surfaces. It is a coating that can be applied to many kinds of plastic moulds. Nibore is also the core used to help unscrew bottle caps
