I. Overview
Our first customer is a leading enterprise of high-tech hydraulic and electrical control presses offers a comprehensive range of bench, floor model, and 4-post configurations. With over 75 years of trusted service, they have established themselves as a premier provider of hydraulic press solutions. Similarly, another top company stands out as a world-class leader in the design, manufacture, and service of hydraulic presses, press brakes, and automation solutions.
In addition, the second customer is an engineering firm and technology company extends beyond traditional machinery manufacturing. They specialize in building hydraulic and servo-electric presses, hydroforming equipment, and automation systems, providing cutting-edge solutions for various industries.
These leading companies rely on Vietnam Outsourcing (VNO), which collaborates with a young, dynamic supplier based in Hanoi City, Vietnam. With 8 years of experience, this supplier excels in mechanical processing, manufacturing, and coating of metal components. Their product lineup includes steel frames and bases for hydraulic presses, meticulously fabricated through welding, CNC machining, surface treatment, and priming (if required). This supplier’s dedication to quality and precision positions them as a notable player in the manufacturing sector, catering to both local and international markets.

III. Challenges & Solutions
The products are hydraulic press frames, which are very heavy and require precise positioning. It is essential to thoroughly review the product requirements in the drawings and develop an accurate machining process. During the implementation, several issues and challenges may arise:
Machining processes
Oil Tank Leakage
Positional Deviation
Weld Appearance Defects
Machining processes
Challenges
Errors in sequencing or machining processes can lead to incorrect positioning of critical assembly points, affecting the product’s functionality for the customer.
Solution:
- Collaborate with the factory to thoroughly review and refine the entire machining process, ensuring precise execution before proceeding.
- Vietnam Outsourcing (VNO) will assist by reviewing challenging stages before implementation.
- Consult with the customer regarding the assembly process and provide repair suggestions.
- Plan and execute corrective actions to ensure product accuracy.
Oil Tank Leakage
Challenges
Incomplete removal of welding slag before leak testing, and the presence of holes or air bubbles in some weld points, resulting in undetected oil tank leakage.
Solution:
- Thoroughly inspect the appearance of welds, especially inside the oil tank.
- Consult the customer’s leak testing system and set up a leak testing unit at the factory.
- Pressure test at the customer’s site: 2 psi
- Pressure test at the factory: 40-50 psi
Positional Deviation
Cause:
Positional inaccuracies during machining result in measured values falling outside the tolerance range specified in the customer’s drawings.
Solution:
Consult with the customer regarding the impact of positional deviations on the assembly process to determine if the deviations are acceptable. Document the findings.
Verify the origin coordinate system according to the drawing requirements before machining to ensure the correct setup of the machining program. Recheck the positional coordinates before tapping
.
Weld Appearance Defects
Challenges
Visual Defects, Weld Appearance Defects
Solution:
- Remove and clean all burrs and sharp edges.
- Thoroughly inspect all weld seams and appearances to ensure there are no missing welds or air holes. Refer to the customer’s welding standards.
- Implement a QC plan for each stage before proceeding to the next step.
