  1. Introduction

Injection moulding is a versatile and widely used manufacturing process for producing intricate and complex plastic components. The precision of the manufactured tools used in this process significantly impacts the accuracy and quality of the final product. Axxicon stands out as a pioneer in the field, renowned for its expertise in precision tool manufacturing and injection (compression) moulding for microstructured and medical polymer products.

 

  1. Precision Tooling and its Impact on Injection Moulding

Precision tooling involves the design and fabrication of moulds that determine the shape, size, and features of the final product. Axxicon emphasizes the importance of precision tooling in achieving high replication yields and maintaining consistent quality. The key aspects that highlight the significance of precision tooling include:

  • Tolerances and Dimensional Accuracy: Axxicon’s tools are engineered to exacting tolerances, ensuring that the dimensions of moulded parts remain consistent and within specifications.
  • Manufacturing limits: Seeking the edge of the manufacturable. Tolerances and precision are only reached by state of the art equipment. Axxicon’s machinery is carefully chosen to reach the best specs and all well maintained in their controlled environment.
  • Surface Finish: The surface finish of a mould directly affects the appearance and texture of the final product. Axxicon’s precise tooling methods result in ultra flat, smooth and flawless surfaces on moulded components.
  • Complex Geometries: Axxicon’s expertise enables the production of moulds with intricate geometries, allowing for the creation of complex parts with remarkable accuracy.

Precision tooling is the foundation of Axxicon’s excellence, defining the essence of injection moulding.
