Wire Mesh Manufacturer in Southeast Asia × MATECH Cast Steel CNC Machining Precision Component

▎Client & Project Overview

Our client is a manufacturer in Southeast Asia specializing in wire mesh products. As the entire equipment required repair and the replacement of cast components, the client approached MATECH to discuss this need.

At the initial inquiry stage, the client had only original samples, no detailed drawings, and he expected MATECH to deliver a complete technical manufacturing solution along with recommendations on suitable wear-resistant materials. Before sending the samples, in order to help the client assess the project budget, MATECH first asked the client to provide photos and videos of the samples, measure the approximate overall dimensions and product weight, and specify the required quantity. Based on this information, MATECH's technical team carried out an evaluation and provided the client with an estimated quotation, together with advice on appropriate materials and manufacturing solutions.

Once the samples were received, MATECH's engineers conducted detailed measurement and, arranged 3D scanning, and held multiple rounds of in-depth discussions with the client. Through this process, the product's technical requirements, manufacturing solution, and a competitive quotation were finally confirmed, and the client subsequently started a business relationship with MATECH.

With MATECH's professional technical expertise and strict quality control, the delivered products have been highly recognized by the client. The two parties continue to maintain a close and strong cooperative relationship to this day.

▎Product Overview: Integral investment casting alloy steel component with CNC Machining and Heat Treatment

• Material: alloy steel 42CrMo
• Manufacturing Process: investment casting + CNC precision machining + heat treatment
• Hardness: 50~55HRC
• Application: this part is for the rebar to slide on top

This component plays a critical role in the client's wire mesh production equipment. To allow the rebar to slide smoothly and consistently over it in the long term, the part requires excellent wear resistance and high hardness achieved by appropriate heat treatment. The material 42CrMo recommended by MATECH, together with the matching technical solution, effectively met the client's operational requirements. Following the successful testing and validation of the samples, the mass production order was successfully launched and delivered as scheduled!

▎Key Challenges

1. Selecting the Appropriate Wear-Resistant Material

Based on the product's function and application, the client requested MATECH to recommend a suitable material, as he was unsure which material would be appropriate. At the same time, he emphasized that the product needed to be highly wear-resistant. Leveraging its manufacturing experience and technical expertise, MATECH proposed the material 42CrMo in combination with heat treatment, so as to achieve the desired hardness and wear resistance.

2. Preparation and Confirmation of Production Drawings

As the samples sent by the client showed multiple worn areas, some dimensions were no longer accurate. To ensure the dimensional accuracy of the part and proper fit in assembly use, after completing the measurement and 3D scanning, MATECH engaged in effective communication with the client and obtained written confirmation regarding the dimensions that were in question on the drawings. The production drawings were ultimately finalized and approved, and were then used for formal production of the tooling and parts.

3. Optimizing the Design to Improve Performance in Service

Based on the groove dimensions provided by the client, MATECH's team carried out an evaluation and found that the groove bottom was too thin (only 3 mm), which could compromise the part's strength and shorten its service life. The design was therefore optimized by increasing the thickness at the bottom. In addition, MATECH recommended changing the tapered groove to a straight one, so that the rebar could pass through smoothly. Through these effective design optimizations, the overall performance of the product in service was significantly improved.

▎Strict Quality Control and Measurement

This steel casting part plays a critical role in the client's wire mesh production equipment, which has demanding requirements in terms of wear resistance, strength, and dimensional consistency. Quality control and inspection must cover the entire process from raw material control, casting production, to finishing machining and heat treatment, and ensure both dimensional accuracy and mechanical properties, as these directly determine the final performance of the casting part in service.

Therefore, MATECH strictly implements the following measures:

• Incoming Material Inspection: All raw materials have to do material certification and composition verification. Only those that pass inspection can be properly stored and released for use.
• Casting Blanks Production: Key parameters in the casting process are strictly controlled to ensure the quality of the blank castings and minimize defects.
• CNC Machining: In-process dimensions are precisely controlled to ensure the accuracy of geometric tolerances as well as the mounting holes and mating surfaces. Critical dimensions of samples and first articles from each production batch are inspected using a Coordinate Measuring Machine (CMM).。
• Heat Treatment: Temperature and holding time are precisely controlled to effectively increase the hardness of the parts.
• Final Inspection of Finished Products: Dedicated gauges combined with precise measurement are used to achieve quantifiable verification of dimensions, geometric tolerances, and hardness.

This strict quality control system ensures that every batch of steel castings meets the client's assembly and use requirements, while helping the client's equipment achieve an extended service life and reducing the cost of subsequent maintenance.

▎Project Results & Delivery Performance

Finally, this cast steel component exceeded the client’s expectations:

• Good assembly fit: The part dimensions are fully qualified and match the equipment, enabling smooth operation without jamming.
• Hardness：51-53 HRC
• Production efficiency: Thanks to the optimized part design, the rebar now feeds through smoothly without jamming, increasing production efficiency by approximately 20%.

These achievements have revitalized the client's equipment with stable and reliable operation. They have reduced the frequency and cost of equipment maintenance, while improving the delivery efficiency of the wire mesh products. They have also created a positive and lasting impact on the client's business development.

▎Why Did The Client Choose MATECH for This Steel Casting Project?
