Industries Using PVD Coating

PVD Coating for Mold Industry

The use of PVD (Physical Vapor Deposition) coating in the mold industry provides many advantages for both mold makers and the mold manufacturing industries. The advantages of PVD coating to the mold industry are:

Wear Resistance:The PVD coating creates an extra layer of protection on the surface of the molds, significantly increasing the wear resistance. This extends the service life of the mold and enables the production of higher quality parts over a longer period of time.
Less Maintenance:The wear resistance provided by the coating results in less distress and damage to the molds, which reduces maintenance needs.
Lower Friction: PVD coatings can reduce the friction coefficient of the mold surface. This allows plastic or metal to flow more easily into the mold during processes such as injection molding and promotes easier release of parts from the mold.
Corrosion Resistance: The PVD coating protects the molds against moisture, salt air and other corrosive elements.
More High Quality Parts: Lower friction and increased wear resistance allow for more consistent, high-quality parts to be produced.
Heat Resistance: Some PVD coatings can maintain their performance even at high temperatures. This is advantageous in hot process molding.
Cleaning and Aesthetics: PVD coating can make the surface of the molds smooth and shiny, which helps the parts look more aesthetic and the molds easy to clean.
Enhanced Release Features: Lower friction allows parts to be released from the mold more easily and without damage. This increases production speed and reduces the number of defective parts.
Longer Mold Life: In general, the protection provided by the PVD coating extends the lifetime of the dies, which increases the return on investment.
Cost Savings: Longer mold life, less maintenance and producing higher quality products save overall production costs.

These benefits help mold makers and users achieve higher productivity, longer equipment life and overall better quality.

Some of the products and components that PVD coating is applied to in the mold industry are:

Injection Molds: These molds used in the production of plastic parts can be coated with PVD coating to reduce friction, increase wear resistance and improve plastic flow.
Casting Molds:Molds used for casting metal, plastic or other materials. PVD can extend the life of these molds and improve casting quality.
Extrusion Dies: These dies are used for metal or plastic profile extrusions. PVD coating reduces friction and can improve extrusion quality.
Stamping and Bending Dies: These dies used to shape metal can be coated with PVD to reduce wear and provide a smoother surface.
Hot Process Dies: These molds can benefit from particularly heat-resistant PVD coatings as they operate at high temperatures.
High Speed Cutting Dies:Tools used for high speed cutting operations can be coated with PVD coating to reduce wear during cutting.
Drilling and Milling Dies:Drilling and milling tools can be coated with PVD to increase wear resistance and cutting performance.
Forging Patterns: Used under high pressure to shape metals, these dies can be coated with PVD coating to increase wear resistance.
Micro-Molding Tools:These molds, which are especially used in the production of precision and micro-scale parts, can be coated with PVD to increase wear resistance and improve surface quality.
Special Purpose Molds: This is a category of industry-specific custom molds, and PVD coating can improve its properties according to the requirements of a particular application.

These applications represent the widespread use of PVD coating in the mold industry. PVD coating optimizes mold performance, while prolonging the service life of the molds, resulting in cost savings.
