Molders that are having their molds built with copper alloys to take advantage of increased mold cooling discovered that copper alloys are easily damaged. When copper alloys are formulated to resist wear, thermal conductivity can be significantly reduced. Molders then were forced to choose between fast cycle times due to increased mold cooling or better wear resistance. Molders that are using copper alloys successfully in molds have learned that float mould components may be the most successful mold design concept to minimize wear. Floating mold components therefore allow the molder to have minimal wear and fast cycle times.

Key to Success

The key issues in floating mold components are to determine which components will be floated and how to actually design them to float. Molders that have successfully determined how to achieve this are seeing faster cycle times and lower mold repair costs.

Our pulp molds have been mounted successfully on the international pulp molding machine, such as reciprocating pulp molding machine, rotary pulp molding machine. And we made many molds for pulp molding machines made by some famous company in the world.

In the process of producing plastic chemical barrel moulds, due to the influence of raw materials, molds, equipment and processes, the surface of the plastic chemical barrel moulds will appear to be blooming. At this time, we need to conduct on-site inspections. The plastic chemical barrel mould manufacturers introduce the process as follows:

Whether the material is wet: check whether there is obvious water and moisture phenomenon in the data. You can visually observe that there is no water and moisture phenomenon in the outer package. Open the material bag and touch the data to see if there is moisture. Difficult to dry.

Many people believe that mold cannot grow on plastic or polymer materials. Mold generally can't break down plastic easily.

However, plastic contains many additives, such as plasticizers, cellulose, lubricants, stabilizers, and colorants to help provide desired features, and these additives ARE very easy for trash can mould to break down.

Once mold becomes established by breaking down the easily digested ingredients, the acids they produce as by-products of growth break down the resin into a more useable food source.

To learn more, read up on the ASTM G 21 test method that describes this process in greater detail.
