Legacy Meets Innovation: How a 40-Year Family-Owned Plastic Manufacturer Revolutionized Operations with Odoo

For nearly 40 years, Engineering Plastic has built a strong reputation in plastic manufacturing. From its inception as a family-run business, Engineering Plastic has passed down its management through generations, preserving core values and industry expertise. 

Over time, it grew into a factory equipped with 70 machines producing an impressive diverse range of products, from automotive plastic parts and food packaging to electrical appliance parts and medical parts. This extensive experience and scale established the company as a trusted name in the industry.

Cracks in the Foundation

 Despite the expertise and growth, Engineering Plastic’s operational processes remained fragmented and outdated. The daily operation depended on disconnected accounting software that lacked integration with manufacturing and inventory systems, forcing teams to manually reconcile data across multiple platforms.

Additionally, error-prone spreadsheets were used extensively for tracking production schedules, materials, and costs, leading to frequent data entry mistakes and inconsistencies.

These manual workflows slowed down decision-making, caused delays in identifying bottlenecks, and created inefficiencies throughout the production line. Inaccurate inventory caused stock shortages or overstocking, which messed up the smooth flow of manufacturing. Furthermore, a critical blind spot in quality control alerts meant that defects often went unnoticed until late stages, which triggered delivery delays and rework.

The combination of these issues frustrated customers who relied on timely, quality deliveries, and it began to impact the company’s reputation for reliability. Internal teams faced constant challenges coordinating across departments, highlighting the urgent need for a more unified, automated system to support growth and maintain customer trust.

Turning Point


Sikrit Ungumphon, the Director, recognized the urgent need for a unified, real-time system to primarily manage workflows especially inventory, purchasing, manufacturing, and quality control altogether. They faced operational challenges that manual methods could no longer handle. This approach effectively addresses issues such as misaligned workflows and a lack of integrated data visibility. These issues started the search for an all-in-one digital solution that could eliminate errors and provide better control.
