Primary processing

Material acceptance

Plastic material, the raw material for molded products, is accepted.
The material's lots and qualities are checked against their inspection certificates.

Material storage

The area where the accepted materials are stored. Over 100 different kinds of materials are stored in each of our factories.
The material tank, dryer, and injection molding machine are connected by a pipe, and working together with production, the material is automatically supplied to the injection molding machine through the pipe.

Production planning

A production plan is formulated upon receipt of orders from customers. The production schedule is displayed on each line's monitor simply by inputting the data into the production planning system.
The production results are also displayed on each line's monitor to allow real-time checking the plan's progress.

Injection molding

Large exterior parts for automobiles are being molded with a large 2,500-ton molding machine.
Moriroku Technology uses 70- to 2,500-ton molding machines in its factories to produce various products of different sizes, shapes, and materials.

Secondary processing

Interior coating

Robots coat the center panel, which is an interior component of the car.
Because customers can always see the interior parts, we manufacture them with extreme care to ensure they are free from contamination or flaws so that we only deliver quality products to them.

Exterior coating

Bumpers, large exterior parts, are coated by large robots. Our exterior coating line can coat products over two meters in length. Up to four different kinds of coats are applied, one over the other, to these products to attain a clear appearance.

Vibration welding

Vibration welding is employed in this step. Vibration welding is a technique that melts and fuses two overlapping parts together using frictional heat through the application of vibration and pressure. To guarantee adequate welding strength, we perform strict quality control through condition management for each piece and strength measurement tests for each production lot.


This is the assembly process for automobile interior parts. We assemble more than 30 types of small parts to the large and complicated injection-molded parts to complete the final products.
In the final inspection, we check the part's appearance and construction from the customer's viewpoint. Then, after performing an open/close check and operation check, the product is finished and good to go.

Quality assurance

The photo shows a testing machine that measures weld strength. To guarantee the quality of products produced each day, we conduct sampling tests of each production lot and record and store the results.


An inspector visually inspects exterior coated parts.
The parts we produce are of high-quality design so we carefully inspect each product for cosmetic defects, dust, external damage, extraneous substances, tarnishing, and other imperfections.


Finished products produced in our factory are loaded onto trucks and shipped.
Products must be delivered at a predetermined time and place, and in the quantity specified.
The containers and carts used to load products are chosen after performing transportation tests for each product to ensure they will not be damaged or deformed during transportation.
