Our Strengths

Injection Mold · 3D
Loading model…

Our top priority is the "mold," the core of our business. We dedicate our resources to continuously improving our molds because we believe that sincere commitment and attention to detail at every stage of the process deliver the highest value and benefits to our customers.

Manufacturing Process

All five processes, from design to mass production, take place under one roof.

Design

Discuss all specifications and requirements with the customer, then adjust the drawings to address any potential constraints or issues that may arise during production.

Machine

Utilize grinding machines, electrical discharge machines, and machining centers to manufacture workpieces into individual mold components.

Inspect

Inspect every detail using appropriate measurement tools to ensure the highest quality of each workpiece.

Assemble

Assemble all mold components together, making adjustments, detailing, and rebalancing the components as required.

Injection

Connect the assembled mold to an injection molding machine and prepare it for mass production.

How Our Molds Are Born and Raised

Because all five processes are under one roof, each of our strengths can span several of them.

01

Manufacturing Molds Optimized for Actual Production

We provide a complete, one-stop manufacturing service under one roof, covering everything from mold design and component manufacturing to assembly and actual injection molding. Our internal PDCA (Plan-Do-Check-Act) system enables us to quickly identify, communicate, and resolve issues within the company, allowing us to continuously improve the quality of our molds.

Our Story

Before we began operating our own injection molding production line, we believed that manufacturing components with the highest possible precision was the key to making the best molds. However, after delivering molds to production facilities, we discovered that it was difficult to receive detailed feedback, particularly regarding production efficiency and mold maintenance.

To address production and mold maintenance issues at their source, we recognized the need for a system that could immediately communicate problems encountered during actual production and use that information to improve the next mold. We therefore established our own injection molding production line and developed our current integrated manufacturing system. In particular, placing our mold design and production teams in close proximity allows them to exchange information immediately. This close collaboration enables us to continuously improve our molds and achieve increasingly higher levels of quality.

Developing and Proposing Ideas for Process Improvement

For us, a mold is not simply finished and delivered to the customer. We believe that continuously maintaining and improving molds can make production smoother and mold maintenance easier. We are therefore constantly looking for ways to improve production efficiency and reduce costs, and we propose these solutions to our customers for consideration.

Examples of Production Improvements
(1) Automation
We proposed and installed an automated visual inspection system integrated with an automated packaging system. This system reduced the number of inspection personnel required and helped lower overall production costs. Normally, inspecting a workpiece requires checking it from multiple angles. When we initially introduced the automated inspection camera system, however, we found that the inspection time was longer than the normal injection molding cycle. By improving mold quality and reducing the occurrence of defective parts (NG) to a minimum, we were able to reduce the number of areas requiring inspection. As a result, we successfully implemented the automation system without increasing the overall production cycle time.
(2) Runnerless / Hot Runner System
We also propose runnerless and hot runner systems as solutions for improving production efficiency and reducing material waste.

In-House Mold Base Manufacturing

We manufacture "mold bases", one of the most important components determining the overall precision of a mold, entirely in-house. After manufacturing, each mold base is measured using a CMM (Coordinate Measuring Machine) to ensure dimensional accuracy. The measurement data is then immediately feedback to our machining team, allowing us to continuously improve our machining techniques and bring workpiece dimensions as close as possible to their target values—even when the difference is only 1 micron.

Careful Attention to Detail from Our Experience in Precision Parts Manufacturing

For every mold component we manufacture, we measure and verify all required dimensions and inspect every critical point on the workpiece. We believe that achieving the highest possible component precision directly contributes to smoother injection molding production and makes it easier to identify and resolve issues during actual production.

Our Story

Since the establishment of our company, we have not only manufactured plastic injection molds, but have also manufactured and supplied a wide variety of individual mold components. As a result, measuring and verifying the dimensions of every component and every critical point has become a standard part of our manufacturing process. In addition to plastic injection molds, we also process a wide range of materials and components, including press mold components, die-casting mold components, carbide, and ceramic parts. Working with such a diverse range of components and materials has allowed us to continuously develop the skills of our technicians and improve our machining techniques, resulting in increasingly higher levels of precision.

Comprehensive Measurement Equipment

Accurate measurement feedback is essential for developing machining techniques and continuously improving mold quality. Our company is equipped with a comprehensive range of high-precision measurement equipment, led by our CMM and other advanced measuring instruments. We convert measurement results that reflect changes in environmental conditions and workpiece conditions during machining into quantitative data. This allows us to identify the optimal machining values and conditions for each individual workpiece.

Continuous Development for the Growth of Our Mold Business
Recruiting new employees and providing continuous training are key elements of our management approach.

Employee Education and Training

Employee Education and Training

We conduct regular training programs designed to develop our employees' analytical and problem-solving skills. Different topics are covered on a rotating basis, allowing employees to repeatedly learn, communicate, and apply what they have learned through hands-on practice. Through this approach, we aim to develop teams capable of thinking critically and solving problems directly on the production floor. This analytical capability at the workplace allows us to steadily accumulate knowledge and develop our manufacturing techniques.

Technology Exchange with Japan

Technology Exchange with Japan

Japan is recognized as a global leader in precision component manufacturing. In particular, our plant headquarters in Japan places a strong emphasis on precision and meticulous manufacturing practices. By sending Thai employees to Japan to learn and gain hands-on experience in an actual manufacturing environment, we are able to significantly enhance the skills, technical capabilities, and technological expertise of our factory in Thailand.
