plastic profile extrusion moulds supplier,High-Quality Extrusion Mold for Precision Manufacturing

When it comes to producing outstanding thermal insulation strips, particularly those made of PA66, extrusion molds are crucial. As an authority in the industry, POLYWELL is known for focusing on the production of molds engineered for thermal break profiles. 

What Are Extrusion Molds?

In simple terms, extrusion molds are used to produce not just an insulation strip, but an entire thermal break insulation profile. Many factors have to be considered including material behavior in processing and dimensional accuracy. Many prefabricated molds can be considered ‘off the shelf’ but PA66 thermal strip extrusion molds are unique in that it deals with high shrink rate material.

The Challenge of Shrinkage in PA66 Materials

PA66 is widely used in thermal break strips for its excellent mechanical and thermal properties. Its biggest flaw however is the high shrinkage ratio when it cools down, which makes it difficult to maintain set dimensions. They must be taken into consideration in shrinkage all through the molding design and the assembly of the parts.

The enhancement of molds’ proportional scaling is POLYWELL’s specialization. This capability is extremely important, especially when taking into consideration the shrinkage of PA66. Instead of simply utilizing the dimensions supplied by customers, POLYWELL engineers use both scientific analysis and thought to anticipate the shrinkage of the material. Specific calculations as well as several decades of experience are used in determining the amount cold molds need to be enlarged.

To ascertain the appropriate oscilloscope proportions set out in the designs can be utilized by post process, however, a rather better approach is having a technical background in this case, industry background information. The effort, time and resources gone into ensuring such expertise makes POLYWELL proud of every designed and manufactured mold. This guarantees to clients that strips of thermal insulations can be produced with the same dimensions anytime they also require them making the clients’ end products improved.

Mold Making for PA66 Thermal Strips

To execute the task, quite an understanding of the material characteristics as well as proper engineering skills are mandatory. Such achievements are when the heat break profiles meet the necessary standard so that the final product can fall among the best in the market, this is simply attained by using POLYWELL molds.
