Finally, these molds are used to create the finished products. Our production team meticulously oversees this process, ensuring the final high-voltage vacuum circuit breaker adheres to the highest standards of quality and precision. It’s through this careful, end-to-end process that we can assure our customers receive reliable and high-quality products, tailored exactly to their needs.

The Process Flow

This extensive process, covering product drawing design, mold building, production, quality inspection, and logistics, ensures that PROAMP consistently delivers high-quality products to its customers worldwide.


The first step in PROAMP’s product manufacturing is the product drawing design. This critical step is handled by a team of skilled engineers and designers. Their primary task is to create detailed blueprints for each product. This involves thorough research and conceptualization to ensure that the product will meet the demands of the market. The process involves several iterations of designs, fine-tuning them based on the product’s intended function, the materials to be used, and other relevant factors. To facilitate this, the design team uses state-of-the-art software to ensure precision and to streamline the process.

Step2: Mold Building

The next step is building the mold. PROAMP’s team of specialized engineers works meticulously to construct precise molds. They employ techniques like CAD and CNC machining to achieve high dimensional accuracy. They pay meticulous attention to detail, ensuring that the molds are made accurately for consistent and high-quality production. The mold building process is a collaborative effort with the design team to ensure that the final product will align perfectly with the designed blueprint.

Step 3:Production and Installation

Production is the actualization of the carefully planned design and precisely built molds. The team uses industry-leading machinery and manufacturing processes to produce components as per the specifications. The production process involves various stages, including casting, machining, finishing, and assembly. After the components are manufactured, the installation phase begins. This involves putting together the individual parts in line with the product blueprint. The team checks for any discrepancies, ensuring that every part fits perfectly and functions as intended.

Step 4:Quality Inspection

PROAMP emphasizes on delivering high-quality products. To ensure this, a stringent quality inspection process is in place. The Quality Control (QC) team scrutinizes each product in terms of durability, performance, and safety. They check if the product adheres to the set specifications, industry standards, and compliance regulations. The QC team uses various testing methods like stress testing, performance testing, and safety tests. Only those products that pass these stringent tests are approved for distribution.

Step 5:Logistics and Transportation

After production and quality inspection, the products are ready to be shipped. PROAMP’s logistics team ensures that the products are packaged properly to prevent any damage during transportation. They organize the inventory, arrange for safe and timely transportation, and coordinate with various parties, including shipping companies and customs. They constantly track the consignments until they reach the customer, ensuring a seamless delivery process.
