MOLD DESIGN

It is a department which takes charge of the period until it builds the drawing of a molded item based on a customer’s needs and can be put into commercial production.

金 型 設 計

It is a department which takes charge of the period until it builds the drawing of a molded item based on a customer’s needs and can be put into commercial production.We receive a completed type drawing, and we make, of course, as we are ordered, but “an aggressive sales style” we make a design and a proposal within our company is our motto.We correctly grasp customer’s needs in the detailed talks as what kind unit a customer wants to make and what kind of molded article is necessary for that, and the drawing is completed as it is paid attention to every detail.

We’re good at forming a part with the relatively simple shape with a high degree of accuracy, so we will seek for the best drawing together while also showing such advantage to a customer.Then, we have the work section make the metallic mold of a trial product, and mass production will start after the customer’s satisfaction.

Mold making is usually requested from outside the company, but our company has a department of metallic mold production in our company.Therefore, since detailed communication is taken, the visitor’s needs can be satisfied quickly. Although balance with cost, etc. must be taken into consideration, of course, what we must not make a mistake is to think at first that “what does a customer expect?”
The concrete design is advanced using two-dimensional CAD and three dimensional CAD properly

METAL MOLDING

In-house-production is our big strength.

金 型 加 工

It is a generally outsourced portion, but our company has an independent metallic mold manufacture section.By taking the smooth communication with the design section which creates a drawing and the production section which actually makes a product, the time from design to a trial production and the mass production can be made faster.Moreover, since the material used for a molded article is special, such as a magnet, in many cases, original technology according to it is accumulated and improved.

Two or more “metallic mold craftsmen” make full use of a variety of machine tools respectively, and complete one metallic mold as technical concentration.Although it is on a case-by-case basis, of course, by the time one kind of metallic mold is completed and it can be produced on a mass-production basis, the required period is about one month.It elaborates repeating correction of details about 4 or 5 times depending on the case.
Of course it is a main premise to make precision highly along a drawing from a design department.Furthermore, delicate ingenuity is put so that the difficulty of molding unique to the special material can be covered with a metallic mold, or each craftsman pursues the original technology.

In any case, it is important whether they can concern for the machine to program to move it, and whether they can be attentive for other posts including the production section.It is this section that can also be said to be the lifeline of our company.

Measures for the constant technical improvement continue.

INJECTION MOLDING

For the most suitable “conditions”

射出成形

Even if we can make the metallic mold in-house which is our lifeline, it is insignificant when we do not complete a real product precisely.

It is very important to repeat correctly and steadily the process of injecting material in a metallic mold and cooling and molding.
Therefore, it becomes a key to calculating “molding conditions.”
The special materials which are the greatest feature as our products limited such as material temperature and tool temperature at the time of molding, and many of them are hard to handle.
However, by accumulation and share of the experience over many years, the best one can be promptly found out of the innumerable molding conditions.For example whoever operates a machine, 1 or 2 products and can be made, but technology of “finding conditions” is necessary to keep producing a highly precise product without taking out a defect as few as possible at a factory of operation for 24 hours.Additionally, how a machine can be efficiently worked as without stopping on the way is also pursued.

Although detailed things may depend on guesswork of a human being with abundant experience, they are also told from seniors to a young people.
Since it is the worksite which actually carries out “craftsmanship,” the scale of its post is about 20 persons as the biggest in our company.We keep making a product with 3 shift systems, and personal teamwork as well as skill is also becoming important.

QUALITY CONTROL

A final process “Breakwater” before delivery of goods

品 質 検 査

We frequently perform “quality patrol” that we extract a molded article and watch it whether a product shipped does not have a malfunction.

We check the appearance or dimensions with various measures as possible in real time and feedback the result in the spot of the injection molding.In our company, when using a special material called a magnet, it is also necessary to check magnetic property.
Even if there are no defects in a product, and it passes smoothly in 5 and 10 years, when there is big failure even once, it’s just a moment we lose reliance.

It is necessary to keep that in mind, and take care so as not to collusion in the same company.Moreover, since the environment which surrounds the manufacturing industry is changing quickly, it is also the feature of this department we always have to develop to respond to any inquiry from customers.
For example, we respond to the various inquiries by whether the specific substance contains into the material purchased and used from a maker, or whether the mineral is not used one mined from the area-of-conflict belt.Unlike a few decades ago, we are now short in competitiveness only by making merely products in comparison with a competitor.

As natural, it is important for high quality which can guarantee something extra.
