V. Mold Design

In designing an automotive tank mold, precision meets innovation and craftsmanship. This is where designers and engineers put on their creative caps in crafting an incredible automotive tank mold. The client’s specifications offer a guide to the mold’s structure, intricate dimensions, preferred material, and other design specifications. 

Nonetheless, TDL embarks on the mold design journey by designing via advanced computer-aided design (CAD) software. The CAD software presents a 3D model of the mold, highlighting the dimensions and crucial features. A prototype is then created for further iterative modifications until it is guaranteed that the design meets all specifications. 

Still, it is important to note that the inclusion of precise gating systems, parting lines, draft angles, and appropriate tight tolerances enhances the performance of the automotive tank molds while ensuring material wastage is minimized. Apart from performance concerns, the molds are also modified to ensure the reduction or complete elimination of impending flaws. 

TDL’s automotive tank molds are crafted and designed with precision and finesse, employing every design technique and technology available at their disposal to fashion tank molds that meet the automotive industry standards. With all design steps fulfilled, they can proceed to the machining molds according to the volume requested by the customer. Let’s see what that entails, stay with us.

VI. Mold Machining

Having completed all pre-mold machining steps, it is time for the actual machining of the automotive tank mold. Remember that attention to detail, precision, and quality is at the top of the mold manufacturing expectations list. 

TDL employs an ultra-modern machining technique that helps achieve the highest standards of excellence along with cutting-edge tools in shaping the best automotive tank molds ever seen. The machining is set off by the machining expert confirming that the materials to be used are of the right specifications and qualities. 

Qualities that include their ability to be machined seamlessly, heat resistance properties, and sturdiness to meet industry standards. Then the machining continues by selecting which methods of machining suit the purpose of the project. Majorly, CNC (Computer Numeric Control) machining is employed, but EDM (Electric Discharge Machining) and WEDM (Wired Electric Discharge Machining) can also be utilized to craft these masterpieces. 

The machinist, being the lead director of this orchestra, decides which technique to deploy. Furthermore, quality control assessments are executed as machining takes place to optimize the machining process for efficiency. This culminates in the assembly of automotive tank molds that surpass the reach as engineers and technicians oversee the mold assembly section. And voila, your automotive tank molds are ready to be shipped.

CMM Mold Inspection 

VII. CMM Inspection

In meeting the highest standards of excellence, a vibrant quality control practice is usually set within the process of mold manufacturing. This is to ensure deviations from the design are detected in time. One such quality control practice is CMM, which stands for Coordinate Measuring Machine. Now, the essence of applying a coordinate measuring machine is to examine the dimensions of the mold for irregularities that should be noted and corrected once detected. 

As we’ve rightly explained, precision in automotive tank mold manufacturing must be at its peak, thus the inspection of the mold using the CMM inspection technology. The machine is set up and adjusted for accurate measurements before ensuring the CMM probes align with the mold. Dimensional accuracy and specified tolerances are measured to be certain they are precise and in line with the design specifications. 

Employing state-of-the-art metrology software, the results of the inspection are analyzed by the quality assurance team. In light of any deviations, necessary corrective measures are implemented and that may entail re-machining affected molds, employing an efficient manufacturing process, and taking steps to avoid future occurrences. TDL is a brand known for its excellent and quality supply of automotive tank molds, and that’s not changing anytime soon.
