Inspection of Machining Allowance
Engineers add extra material, known as machining allowance, to molds and dies to ensure their sizes, accuracy, and surface finishes meet technical specifications. By doing so, defective product rates can be substantially reduced. SCANOLOGY’s 3D laser scanners can measure the rough mode and identify if there are enough machining allowances for the parts to be machined. This way, the solution helps manufacturers to precisely monitor the manufacturing process to ensure products are made with minimum material to reduce costs and increase efficiency.
Optimization of Machining
There is a slight difference between the machining allowances of the mold manufactured and the nominal one. The CNC machine fails to remove metal layers thinner than the preset parameter, which results in wasted processing time and increased machining costs. By obtaining the actual machining allowance of blanks, manufacturers can set precise parameters for removing machining allowance. It helps manufacturers increase production qualification rate and shorten mold manufacturing cycles.
Post-machined Mold Inspection
The molds precisely-machined may differ from the theoretical model due to the inferences of real-life manufacturing environment. When the molds or dies are manufactured, attributes such as mold width, height, depth need to be measured. Non-contact 3D laser scanners can measure parts with complex features such as narrow areas, slots, curvature and concave surfaces. Full-field and accurate data of parts can help to verify the quality of parts and serves as data basis for the subsequent mold trial.
Mold Trial
Mold trail is the process by which a new mold is optimized so that it can produce qualified products. Molds need to be corrected when there is a large gap between upper mode and lower mode. Mold builders analyse and adjust the mold iteratively to meet the technical requirements and be used for making qualified products. Using 3D scanners, engineers can accurately identify the value of gap so that they can adjust the gap accordingly. Thanks to their high-speed scanning capabilities and high accuracy, 3D scanners can aid in identifying unqualified areas by capturing full-field data.
Mold Repair
After being used in high-volume manufacturing, molds are subject to wear which leads to increasing defect rates of parts manufactured. Portable 3D laser scanners can be used to measure the molds and compare them to original 3D molds. The deviation and worn areas can be precisely identified with quantified values. Therefore, designers and manufacturers can monitor the molds in time and take responding corrective actions to repair molds, which helps to increase efficiency and optimize workflows.
Mold Archiving
A digital archive is a method that produces detailed geometric representations of real-world items. The practice of digitally backing up items is becoming more and more popular. By 3D scanning, the qualified wood molds, casting dies, and forging dies can be digitized as reliable and comprehensive basis for mold repair. The mold corrected can also be used to update the design drawing. 3D scanning helps to archive molds and dies for further use.
