PR message
Miyuki is a company that designs and manufactures molds for plastic molding in Takaoka City, Toyama Prefecture. We have a track record in unscrewing of foods, pharmaceuticals, medical equipment, cosmetics, others (motors, racks, etc.), large number of molds using hot runners for round products, and molds for engineering plastics and super engineering plastics with complicated mechanisms such as automotive and semiconductors.
We manufacture molds with particular attention to processing accuracy that lead to shorten the construction period of T0 to the beginning of mass production (reduce the number of TRYs). We are highly rated for our high durability, cycle-up, and trouble-free during mass production molding. In addition, we can handle mold prototype production of 50 to 450 tons to prototype TRY, so even for distant customers, it is possible to order molded products only without frequent mold traffic.
Spout
Industry: Food-related industry
Resin used: PP
Gate: Hot runner valve pin (Seiki Corporation)
After finishing the processing of the mold base, we asked Seiki Corporation to incorporate it, then we incorporate hot runner.
As shown in the picture, there are many wires due to many valve pins.
It's hard to handle it in a very narrow place,
but since we were used to it, we completed it in one day.

Product name: Screw cap
Industry: Food-related
Molded material: HDPE (High Density Polyethylene)
Molded product size: Φ20x20mm
Gate method: Hot runner, valve gate
Mold specifications: Fixed side cavity cooling, unscrewing jet water cooling
Steel: HPM38 quenching
Molding machine size: 180t
We handle the manufacture of screw caps (tamper-evident cap) molds. We have track record of manufacturing many multi-cavity hot runners and valve gate type molds.
To eliminate the undercut, we use unscrewing method and slide mechanism, and install cooler on the insert that work as a mold to improve the molding cycle

Product name: Spout straw
Industry: Food-related industry
Molding material: HDPE (High Density Polyethylene)
Molding size: 20x60 (inner diameter 9)
Gate method: Hot runner, valve gate
Mold specifications: 2-plate structure, core cooling
Steel: HPM38 quenching
This is a molded product with a straw attached to the spout, used in food retort pouch. The straw length is 60 mm.
With hot runner specifications, it become runner less and also leads to shortening the molding cycle.

The processing of mold base, insert, etc. of spout multi-cavity mold is almost completed, so next we will incorporate it at hot runner maker (Seiki Corporation).
Since we have produced many similar molds so far, we believe that we can manufacture it without any trouble.
Next, we plan to deliver cap multi-cavity molds that manufactured using mold base (including hot runner) we made in the past.

It is a prototype we designed recently.
In a general design, the product part and its peripheral mechanism part are 3D, and other mold bases are designed in 2D. But to save space and when it is difficult to tell the details to customers, according to the customer's request we may design the entire mold in 3D.
It takes some time to manufacture, but it is a great benefit since it can prevent misunderstanding.

Since it was a difficult shape to start with the normal unscrewing on the movable side,
so we have completed a mold with unscrewing set up inside the slide.
We connect the gears and rotate them with a motor.

We made a mold for food-related resin cap with fixed side slide and unscrewing structure.
This is an updated mold made by another company,
We will have briefing with customers, listen to issues and requests regarding the current mold and will design it.
