山田精工 List of Products and Services

We would like to introduce our unique technology, "High Cycle Molding." This technology utilizes a large number of small molding machines, primarily in the 7t and 15t classes, with a maximum capacity of up to 50t, allowing for high-speed mass production. It can produce the same number of products in the same time as large machines. We solve problems such as "unable to meet deadlines" and "want to mass-produce from prototype models." 【Features】 ■ Pursues manufacturing cycles to the extreme, achieving shortened delivery times ■ Capable of mass production from prototype models ■ Increased production speed through modifications for multiple cavities ■ Proven lifespan of prototype and mass production molds exceeding 4 million shots *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce examples of simple shapes (short delivery time) and complex shapes (short delivery time and long lifespan) that we have produced. The fuse and relay case parts with simple shapes were completed in 4 days, while the smartphone camera parts with complex shapes were finished in 2 weeks. Even with short delivery times, we aim for high quality without any compromise. If you would like samples, please feel free to contact us. 【Overview of Examples (Partial)】 ■ Fuse and Relay Case Parts <Simple Shape (Short Delivery Time)> - Material: High-temperature LCP, PA resin - Features: Precision, simple shape - Guarantee: 2 million shots performance *For more details, please refer to the PDF document or feel free to contact us.

Do you have concerns regarding precision and quality, such as "I want to achieve precision in parts" or "I want to reduce defects"? Our unique technology stabilizes quality by reducing the number of cavities. Our adjustment technology at the micron level achieves an astonishing dimensional tolerance of ±10μm, with ultra-thin wall formation having a partial wall thickness of 0.1mm and flatness within 0.01mm. 【Examples of Achievements】 ■ Thin-walled molded parts for smartphones and PCs ■ Microscopic bobbins weighing 1/10,000 of a gram ■ Stable quality for small quantities of extremely small parts *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the pre-analysis conducted with 3D models at our company. This service is ideal for those who want to "try new materials" or "are unsure about suitable materials." Through warpage analysis, injection pressure analysis, and gate position analysis, we can achieve cost reduction and predict shapes. Additionally, we also accept inquiries solely for flow analysis services. 【Features】 ■ Proposals for materials and shapes anticipating the finished product ■ Short delivery time until report submission ■ Improved mold accuracy ■ Inquiries for flow analysis services only are also possible *For more details, please refer to the PDF materials or feel free to contact us.

We offer the sale of core molds separately. Since we only manufacture core molds, we can reduce mold production costs by 30% and shrink storage space by 70% (compared to in-house). Our core molds are compatible with a unique manufacturing method that supports multiple cavities and multi-face slides. Additionally, we have adopted an "integrated slider structure" that makes assembly easy, allowing for smooth parts adjustment and mass production. 【Features】 ■ Prototype molds can be used directly as production molds ■ Mass production with small molds ensures low cost and speed ■ Parts adjustment is possible for each cavity ■ The shared base created once can be reused (next time, only the core mold will be produced) *For more details, please refer to the PDF document or feel free to contact us.

A micro-molded part measuring 15mm x 15mm or smaller, which is part of a camera module. It requires strict dimensional accuracy and flatness to be combined with other components. To accommodate the high performance and thinness of cameras, each part has been miniaturized, becoming thinner than an average thickness of 1mm, making it more susceptible to warping and deformation. Through years of accumulated know-how, we design molds that consider post-molding defects and respond with micron-level precision machining technology. If you have products that require precision or are troubled by defects such as warping or deformation, please feel free to contact us.
