01.Production Engineering

01.Production Engineering

Our motto is: Safety, high quality,
and high efficiency.
Our job is to design and develop
superior tools and jigs for superior
production.

We ask workers on the front lines what problems they are having, then design and develop the tools and jigs to meet the plant's production needs. As a department which is directly tied to improving productivity, we have taken the lead in designing and refining production processes with the aim of ensuring efficient and safe manufacturing regardless of who is engaged in the task.

02.Incoming Inspections

02.Incoming Inspections

We thoroughly inspect the parts
being introduced, to ensure the
highest level of quality for
mass production.

We inspect all areas including the measurements, strength, and the exterior of all new parts in detail, to ensure they meet the requirements of the design drawings. Our inspections are extremely strict, checking for contamination with microscopes and confirming the dimensions with 3D measuring instruments. A single part can affect the productivity of the whole plant, so we work to maintain accuracy with repeat inspections if we find something wrong.

03.Assembly Picking

03.Assembly Picking

There are over 2,000 kinds of parts
handled in this area.
For each product, the right set of
parts is sent to the right
manufacturing process.

The number of parts required for a single machine is around 400. The parts required for each process are sorted into sets and supplied to each line. Parts management was partially systematized from 2015 to make the supply of parts more efficient.

04.Presswork

04.Presswork

We utilize presses of up to 1,000-tons
together with 3D lasers.
We produce parts of all shapes
and sizes here.

This process turns steel plates into parts. Massive presses up to 1,000 tons and 3D lasers are used to fabricate all sorts of parts, from those weighing 130 kilograms, to ones small enough to fit in the palm of your hand. We utilize Yanmar Construction Equipment's proprietary pressing technology to form 1.6 millimeter steel plates into deep concave shapes, like that of a saucepan.

05.Welding(Thin)

05.Welding(Thin)

What we look for is a beautiful
and airtight finish.
We handle parts like covers or
fuel tanks that are up to
4.5 millimeters thick.

We weld thin steel plates from 2.3 to 4.5 millimeters thick. Generally, we handle parts that require exterior quality, like covers, or parts that need to be airtight, like hydraulic fluid tanks. We try to ensure top quality by conducting submerged water visual inspections, which use air pressure to check for any leaks, and machine wash parts to remove dirt that is invisible to the naked eye.

06.Welding(Thick)

06.Welding(Thick)

Welding heavy parts up to 50 millimeters
thick that require strength.
Humans and robots work together
to ensure precision.

We weld thick steel plates from 4.5 to 50 millimeters thick. I work the rotating drive parts, which are essential elements of construction machinery. Robots handle tack welding, while humans weld the detailed areas. Welding requires a high level of skill, and therefore proficiency examinations are held twice a year in the workplace to further improve our technique.

07.Painting

07.Painting

Singlehandedly performing the entire process,
from mixing and preparing the paint to
finishing the fine details.
The task is to make the exterior
of the machine - its “face” - look
as good as possible.

100 to 170 parts per machine are sorted into three lines by drying temperature: high, normal, and low. Mixing paint for rustproofing and painting the fine areas that machines cannot handle is all done by hand. As a process that affects the exterior quality of the product, it requires a great deal of skill to cover the entire surface evenly with a coat only 0.06 mm thick.

08-1.Backhoe Assembly

08-1.Backhoe Assembly

Assembling all the backhoes to be
manufactured on a single line, from 0.5t to 10t.
An elite team of workers combine
inspiration and technology to
assemble the backhoes.

Currently, there are 16 models in the backhoe product line. The specifications are different, for the countries where they will be used, and as requested by customers, so in fact there are over 200 different patterns. The assembly of all of these on a single line is one of the unique features of Yanmar Construction Equipment. Each process takes around 7 minutes, passing on the machine to the next process without any delays.

08-2.Loader and Carrier Assembly

08-2.Loader and Carrier Assembly

Manufacturing 1t and 5t machines
on a single line. Employees fully
focused on quality work
together to complete
the machinery.

Painted parts, purchased parts, and other parts are sorted into eight processes for assembly to complete the loaders and carriers. In order to improve our production efficiency, we introduced a conveyor line in 2016. There are fewer parts compared to backhoes, so while the number of employees is smaller, each member of this elite team plays a pivotal role with many responsibilities keeping them on their toes as they work.

09.Delivery Inspections

09.Delivery Inspections

We need knowledge of all the
processes and models.
In order to satisfy our customers,
absolutely no compromise
is allowed.

In this process, we inspect the exterior and the functioning of the assembled machines. We check every single point, from scratches in the paint, to the tightness of the bolts, mistakes in assembly, or oil leaks. We make sure to actually operate the machines just as they will be used in real life.
