Mold Manufacturing

PMT Provides Ideal Measurement Solutions for the Mold Manufacturing Industry.

With the rapid development of the processing and manufacturing industry, high-speed machining skills have been increasingly applied to the processing and manufacturing of machine tools and molds. As an important part of modern industry, the machine tool and mold manufacturing industry require high measurement technology. For example, the mold, as a precision tool, is playing indispensable role in modern society, and a single car needs more than 20,000 molds. Therefore, molds are vital to mass production. The development of mold production is also one of the important indicators of a country’s machinery manufacturing capability.

  • Coordinate Measuring Machine(CMM) has the characteristics of high precision, powerful function and good versatility, and is the standard measurement choice for most machine tools and mold enterprises in the quality inspection process. It can detect the diameter and position of the specified point, assembly and positioning hole, etc., and is often used to measure the contour of plane and line. housing, so as to maximize the effective measurement range.
  • Similar to CMM, Portable Coordinate Measurement Machine(PCMM) has the accuracy of up to 0.02mm, which is also known as the mobile CMM. The portable CMM has the characteristics of easy installation, efficient measurement, and detection anytime and anywhere. This measuring arm can be mounted directly on a large mold base or mold base plate for measurement, thus avoiding the waste of resources such as hoisting and using fixed CMMs.

Different Mold Types

  • Injection Molds

Injection molds are molds used to produce plastic products, and their precision and dimensional stability are essential for product quality. CMM can accurately measure the dimensions and shapes of injection molds to ensure they meet design requirements. For molds with complex shapes, non-contact measurement method such as laser scanning can be used for 3D measurements; For molds with simple shapes, contact measurement method such as a coordinate measuring machine is used.

  • Die-casting Molds

Die-casting molds are used to produce metal castings, such as aluminum alloys, zinc alloys, etc. CMM can perform detailed measurements and analyses of die casting molds to ensure they meet production requirements. The shape accuracy of the die-casting mold requires that the shape of the cavity, core and other components of the mold be consistent with the design drawings, and there is no obvious deformation or deviation. Positional accuracy requirements as well as the relative position relationship of each component in the mold must meet the design requirements to ensure the shape and position accuracy of the die casting.

  • Other Molds

In addition to the common mold types mentioned above, coordinate measurement machine can also be used to measure other molds, such as rubber molds, ceramic molds, glass molds, etc.

Adaptable to Complex Environments

In mold making, the measurement environment is often complex and changeable.The portable CMM is small in size, light in weight, easy to carry, and can adapt to a variety of complex measurement environments. Whether on the shop floor, in the lab or outdoors, portable measurement arm can deliver superior performance and ensure the accuracy and reliability of measurement results.

Adaptable to Complex Environments

Complex Surface Measurement

Molds often have complex curved surface shapes, which are difficult to accurately measure with traditional measurement methods. Portable CMM, however, are able to solve the problem and analyze complex freeform surfaces by collecting large amounts of point cloud data. This is especially important in automotive body molds, aerospace parts molds, and other fields to ensure the accuracy and consistency of the surface shape of the mold.

Complex Surface Measurement

Rapid Measurement

The portable CMM has the ability to measure and detect quickly, which greatly improves the measurement efficiency. Meanwhile, by presetting inspection programs, the machine can efficiently perform batch inspections, which is of great significance for quality control and yield improvement in the mold manufacturing process. Through rapid measurement, customers can detect problems in mold manufacturing in time and take corresponding measures to improve the process. This will help manufacturers shorten the production cycle and improve production efficiency.

Rapid Measurement

Diverse Measurement Methods

Portable CMM is usually equipped with multiple sensors, such as laser scanning head, touch probe, etc., making it more flexible to meet different measurement needs. The diverse measurement methods enable the portable CMM to cope with a variety of complex scenarios and meet the diverse needs of mold measurement. For example, in the measurement of mold cavities, a laser scanning head can be used for non-contact measurement to avoid damage to the mold; In the measurement of the critical dimensions of the mold, the touch probe can be used to ensure the accuracy of the measurement results.

More Precise Measurement

In the mold manufacturing process, the accuracy of some parameters is critical, which requires the use of micron-level coordinate measuring machine. PMT bridge CMM is an ideal choice for small and medium-sized molds. Customer can clamp the parts directly and fix them on the platform for inspection, and the standard threaded holes on the platform can help fix the fixture on the platform. The PMT LOONG gantry CMM can measure very large and heavy molds with a more open structure, no platform support, and no load-bearing restrictions.

 

Automatic Detection

The coordinate measurement machine can realize batch measurement automatically in the process of mold processing, which is of great importance in mass production.

Key Size Measurement: In the mold manufacturing process, the key size of the mold needs to be accurately measured. The CMM can achieve fast and accurate measurement of the key dimensions of the mold.

Reverse Engineering: Portable CMM can also be used for reverse engineering of molds. By 3D scanning and measuring of the mold, the 3D data of the mold can be obtained and the corresponding 3D model can be generated. This provides strong support for the design, manufacture and modification of molds.

Mold Cavity Measurement: The coordinate measuring machine can be used for accurate measurement of the mold cavity. By measuring the size and shape tolerances of the mold cavity, visual reports such as color difference maps can be generated to get to know the wear and deformation of the mold. This helps to detect wear and deformation of the mold in time and take corresponding repair measures.

The combination of portable CMM and fixed CMM complements each other very well, which can meet almost all precision measurement needs for different molds.
