Business Areas

• Prototype One-Stop Solution: Jinyoung Proto Co., Ltd. performs all processes of prototype production in-house as a one-stop solution, including (reverse) design, casting analysis, wooden patterns, molds, casting, inspection, precision machining, CMM measurement, assembly, and shipment. This allows for quick responses to problems that may arise during the production process and enables efficient manufacturing.
• Precision Casting and Machining: Utilizing the sand casting method, we professionally produce complex, precise, and high-difficulty products according to the designer's intent. Through casting and machining processes for aluminum and cast iron products, we produce various advanced technology products such as automotive parts, marine parts, and medical device parts.
• Wooden Pattern Production: We independently produce wooden patterns used in sand casting, which allows for short-term product production and easy modification of products and casting methods.

Products

• Powertrain Prototypes: We produce aluminum and cast iron-based powertrain prototypes through casting and machining processes. We custom-produce and supply perfect products tailored to customer requirements, including complex shapes and tight tolerances.
• High-Difficulty Precision Parts: We produce high-difficulty products requiring high precision and technical expertise, such as transmission cases, turbine housings, hydraulic machinery, and NVH-related parts. We are also participating in 8-speed DCT and 10-speed DCT projects.
• Key Components for Advanced Technology Products: We are developing key components for advanced technology products that form the foundation of future industries, such as cooling solution parts for hybrid cars, hydrogen cars, and electric cars, as well as dental and diagnostic medical devices.

Special Notes

• Full Process In-line Production System: All processes, from design to wooden patterns, casting, machining, measurement, and assembly, are established in-house, allowing for quick responses to any issues that may arise during the production process. This enables efficient work and fast delivery times.
• High Quality and Short Delivery Times: We produce high-quality prototypes that go beyond the concept of general prototypes, faithfully performing all functions envisioned during design, exceeding mass production quality. Furthermore, by delivering in a shorter period compared to competitors, we minimize customer losses and ensure the continuity of research activities.
• Accumulated Technical Know-how and Cost Efficiency: We have dedicated over 10 years to casting and prototype production, accumulating technical know-how and reducing defect rates through continuous process improvement. Our efficient in-line system minimizes development and failure costs, providing economical solutions.

Recruitment Information

• Main Hiring Positions: We primarily recruit for roles such as general workers in manufacturing, product assembly, leak inspection, surface treatment, and product shipment, and also recruit for sales management and client management positions.
• Benefits: We operate four major insurance and pension schemes, including National Pension, Employment Insurance, Industrial Accident Compensation Insurance, Health Insurance, Retirement Pension, and Accident Insurance. We have leave/holiday systems such as 5-day work week, annual leave, regular holidays, congratulatory/condolence leave, reward leave, and parental leave.
