Challenges in “Arrangement, Procurement, and Assembly” for a manufacturer of optical-unit-embedded products

 

Recently, Toyotec has been consulted by a global manufacturer of commercial equipment, and the theme of our service is “integrated production support”.
In this article, we will focus on this “integrated production” and explain the benefits to customers and the value that TOYOTEC can provide.

 

Suppliers spread across multiple plants, complicating management, assembly costs and lead times

 

The customer faced an issue on the impact of the “dispersion of suppliers” to various areas.

Suppliers and factories has spread out throughout the Asian region, with TOYOTEC producing the lenses, Company A in Vietnam producing the product housings, Company B in Japan producing the optical sensors, Company C in Korea producing the machined parts, and the assembly plant in China.
In particular, when irregularities occurred, such as the release of a new model or the sudden receipt of an order from the head office to increase production of a particular model, the procurement staff were forced to use all kinds of means, such as e-mail, fax, and telephone; and production deadlines were rapidly increasing.

The impact of the problem was noticeable during production launch of a new model, when there were many parts whose production quality had not yet been stabilized, and the amount of work involved in returning defective products to the production plant, requesting additional production, adjusting delivery dates, etc… They were extremely confusing and interfered with normal operations.

The customer was looking for a new company that could handle all the procurement-related work, but could not find one that could handle the arrangements, procurement, and communication with satisfactory quality, so the manufacturer’s procurement staff had no choice but to take on this work.

 

90% reduction in man-hours, thanks to TOYOTEC’s integrated production proposal.

 

TOYOTEC’s sales staff already had an idea of how difficult it was to make arrangements and give assembly instructions from each supplier. One day, we had an opportunity to actually hear about the difficulty of the work through communication with the person in charge of procurement. We suggested that TOYOTEC could provide integrated production services. 

TOYOTEC has production and assembly plants in China and other parts of the world, and also has a wealth of experience in OEM and other in-house production. In the past, TOYOTEC has produced complete sets of lenses for consumer SLR cameras, and has a long track record in parts arrangement and assembly.
We also have an assembly plant skilled in performance evaluation and quality correction, as it is impossible to evaluate the quality of a lens until the unit is assembled.

Therefore, we have decided to use our production technology to carry out some of the production at our customer’s plants in China at TOYOTEC’s China plant. As a result, the number of man-hours required by the person in charge was naturally reduced, and both yield and lead time improved, leading to the person in charge receiving an award from the head office for the improvement.

Today, TOYOTEC’s assembly deliveries have increased more than tenfold, and the staff in charge is able to devote more time to the procurement of new and important models that requires more energy and man-hours. According to the staff member in charge, the man-hours required for the normal flow of products has been reduced to about one-tenth of what it was at one time, and he still thanks us every time we meet.

If you are concerned about the high man-hours required for procurement and arrangement, please contact TOYOTEC.
