Marlon advised PROTO MFG on conducting regular quality control checks during the production process. Quality control checks involve inspecting machined parts to ensure that they meet customer specifications and industry standards. Marlon emphasized the importance of using quality control tools and techniques such as calipers, micrometers, and CMMs to verify the dimensions and tolerances of machined parts. He also recommended implementing statistical process control (SPC) to monitor variability in the production process and identify and correct defects before they cause quality issues.

Marlon also spoke about pricing evaluation of machined parts. He advised PROTO MFG to adopt a cost-based pricing strategy, which involves determining the total production cost (including direct material, direct labor, and overhead costs) and adding a reasonable markup to cover profit and risks. Marlon cautioned against relying on market-based pricing, which involves pricing machined parts according to market trends and competition, as it may result in suboptimal pricing that does not cover production costs or result in lost business opportunities due to pricing too high.

Marlon also advised PROTO MFG to focus on reducing production costs by implementing lean manufacturing practices. He recommended using value stream mapping and continuous improvement techniques such as 5S, Kanban, and Kaizen to identify and eliminate waste (such as overproduction, unnecessary transportation, and inventory). Marlon cautioned that reducing production costs should not be at the expense of quality control and advised PROTO MFG to strive for a balance between cost-saving and quality.

In addition, Marlon spoke about the importance of communication between the customer and manufacturer. He advised PROTO MFG to establish clear channels of communication with its customers, such as regular meetings and progress updates, to ensure that both parties are on the same page regarding project timelines, specifications, and any changes in requirements. Marlon emphasized the need for transparency, honesty, and trust-building between the customer and manufacturer to foster a long-term partnership that benefits both parties.


In conclusion, Marlon’s advice to PROTO MFG on quality control and price evaluation of machined parts provides valuable insights that mechanical engineers, buyers, and designers can apply to their projects. By focusing on regular quality control checks, cost-based pricing strategies, lean manufacturing practices, and effective communication with customers, you can ensure that your project results in high-quality machined parts that meet customer specifications, industry standards, and budget constraints.
