Machine and equipment meeting diversified requirements
including cost reduction and short delivery time

An extensive list of machine and equipment installed meeting such requirements as cost reduction, short delivery time and many kinds in small quantities production

Here is an extensive list of machine and equipment installed at Kuzuhara Gomu, the company providing support for rubber molding and processing from the production preparation stages such as material selection and designing. To enhance our capabilities for our customers, we have a multiple number of equipment with the equivalent machine specifications: e.g. we currently have six units of a large (300 ton vacuum) molding machine against one or two units usually installed by our peer rubber processing company.

Rubber Cutter

  • Rubber Cutter
  • Rubber Cutter

The rubber is cut to an appropriate size and weight so that it can be inserted into a mold. The spacing for feeding the rubber into the NC Cutter is programmed to ensure the rubber is cut in consistent dimensions.

Rubber Molding Machine

  • Rubber Molding Machine
  • Rubber Molding Machine

Our molding machines have the production capabilities from 70 ton to 300 ton. Each machine is equipped with a semi-automatic mold disassembly device, permitting a high working efficiency to realize a high precision work. Our vacuum molding machine is so operated as creating vacuum inside the chamber before the mold is set and pressurizing it; this molding process prevents air scratches on the work from occurring. Each molding machine has a program memory function installed, permitting a precise storage of configurations and dimensions of the work for processing. This function of our molding machines is the “secret” in that we can strive for zero defects products.

Rubber Finisher

  • Rubber Finisher
  • Rubber Finisher

Liquid nitrogen freezes the work in the chamber of the machine in the range of minus 30℃ to minus 120℃. Under such frozen condition, the media are injected, removing burrs of the work. A conventional deburring is by hands, but our automated process realizes a short processing time of the work at a stable quality, leading to overall cost reduction.

PICK UP!A must-see information for our peers: we could accept an order of a freezing shot treatment or a freezing tumbler treatment only.

For the benefit of our rubber processing industry for its growth, Kuzuhara Gom has just started services for such treatment as the following in use of our equipment available. These special services should help our peers assure their product quality.

Freezing Shot Showa Denko Gas Products Co., Ltd. ULTRA SHOT NS 7,000cc 1
Freezing Tumbler HISIMURA NT120 60,000cc 1

Heat Treatment Machine (Secondary Vulcanization)

Heat Treatment Machine (Secondary Vulcanization)

A rubber is heat-treated for long hours at the temperatures between 80℃ and 200℃. The treatment by the machine removes its odor and vaporizes its residue as well. For example, low-molecular siloxane which remains within the rubber component can be removed from the component by such heat treatment of high temperatures for long hours.

FANAC ROBODRILL α-D21SiB5

FANAC ROBODRILL α-D21SiB5

Small size cutting machine with high speed, high precision and high efficiency capabilities – our new investment enables us to do an in-house die make for prototype and product development, leading to reduction in both production lead time and cost.

Microscope for measurement

Microscope for measurement

Measurement by hands using a caliper or a dial gauge may result in dispersion of its results caused by an added force by a measurement operator. By using a contactless measurement method, we can prevent such dispersion and achieve more precise measurement. An image system is mounted on our instrument which can handle the measurement up to the 0.0001 (1/10,000) of a degree.

Flatness Inspection Machine

Flatness Inspection Machine

This machine, using an actuator installed, measures the height of the rotating work in use of a laser displacement meter. In order to enhance the quality of a rubber valve which is used under the environment where the valve is compressed by a low stress, we conduct a 100% in-line inspection by measuring the correlation between its flatness/height at the valve center and the height of its periphery. This gives the quality assurance of the rubber valve.

3DCAD (Three-dimensional design system)

3DCAD (Three-Dimensional Designing System)

We can apply our system in any industrial field to support from the design/development stage.

High precision image dimension measuring instrument

High precision image dimension measuring instrument

Our new measuring instrument allows anyone to simply use at high speed with high precision ±0.1μm . It also helps us to make quality assurance for production products requiring dimensional measurement. Its high speed measurement can shorten lead time of any samples off dies under development.
