ジャノメダイカスト株式会社 List of Products and Services

Janome Die Casting's gypsum casting was born from a unique and innovative idea, achieving a short lead-time prototyping method that reduces waste in prototype evaluation during the development stage by shortening and enhancing precision in the development period. We can provide cast products with the same level of surface finish and thin walls as die casting in a short period (short lead time)! It is suitable for prototyping die-cast products and small-lot production of parts at die-casting levels. This time, we are unveiling "The Basics of Gypsum Casting," which clearly outlines the gypsum casting process of Janome Die Casting! It provides detailed explanations of the characteristics, properties, and precision of gypsum casting with photos and graphs. **Features of Janome's Gypsum Casting** - Short lead times (can ship in as little as 7 days if 3D data is provided) - Low cost due to the use of simple molds - Smooth surface finish comparable to die casting due to gypsum molds - High freedom in mold structure allows for undercut shapes - Capable of producing thin-walled products at the same level as die casting, with a track record of 0.5mm thin-walled products **Contents of the Materials** - What is gypsum casting? - Manufacturing process - Precision - Size and material - Mechanical properties and thermal conductivity (reference values) *For more details, please request the materials or view the PDF data from the download.*

Our company offers mass production die casting (aluminum and magnesium) as well as prototype services through precision gypsum casting (aluminum, magnesium, and zinc). "The prototype went well, but there were many issues during mass production..." "We have to create separate drawings for prototypes apart from the mass production drawings..." We can solve these concerns. We will help identify issues related to transitioning from prototype to mass production at the prototype stage, ensuring a smooth transition to mass production. This catalog introduces solutions to three common problems encountered in prototyping. [Contents] ■ About Janome Die Casting Co., Ltd. ■ Three Common Problems in Prototyping - Solution 1: Identifying issues during mass production - Solution 2: Reducing the burden on designers - Solution 3: Integrated support from prototype to mass production ■ Summary ■ Case Studies ■ For inquiries regarding estimates and considerations... *For details, please request materials or view the PDF data from the download.

At Janome Die Casting, we established a gypsum casting prototype center in April 2012. We quickly identify and address issues in mass production! We can cast complex shapes and those with fine surface irregularities, reproducing regular protrusions and depressions with a spacing of 0.2mm down to 12μm. This is suitable for prototyping die-cast products and small-lot production of die-cast level parts. 【Features】 - Short delivery times (can ship in as little as 7 days if 3D data is provided) - Low cost due to the use of simple molds - Smooth casting surface comparable to die casting due to gypsum molds - High freedom in mold structure allows for undercut shapes - Capable of producing thin-walled parts at the same level as die casting, with a track record of 0.5mm thin-walled products *For more details, please request materials or view the PDF data available for download.

Although it is a prototype, the same three major characteristics as mass production can be achieved. 1. Realization of mass production shape: setting of draft angle and protruding pin position 2. Achievement of a hard chill layer on the product surface 3. Realization of the same density balance as in mass production

• Other Auto Parts

We will prototype aluminum parts using die casting. Under the mass production conditions of die casting, we can prototype the die casting alloy ADC12 with the same properties as in mass production.

We can accommodate everything from gypsum casting without molds (ideal for small quantities) to full-scale mass production die casting (thousands to tens of thousands of pieces). We will propose the most suitable manufacturing method based on your requirements. 【Optimal cases for gypsum casting】 ○ I want to create prototypes comparable to die casting in a short period and with a quick turnaround. ○ I want to produce parts comparable to die casting in small quantities and small lots. 【Optimal cases for mass production die casting】 ○ A product has been completed that is ready to be launched in the market. ○ The quantity is expected to be suitable for mass production. ● For more details, please contact us or download the catalog.

• Other Auto Parts

We manufacture aluminum die-cast alloy (ADC14) parts with excellent wear resistance. They are suitable for parts that require sliding properties.

• Drive system parts

We manufacture die-cast aluminum alloy parts with 15% zinc-rich composition that excel in wear resistance. They are suitable for parts requiring sliding properties.

• Drive system parts

The aluminum dross pressing device is an energy-saving apparatus that separates and extracts aluminum by rotating the dross (slag) produced during the purification process while it is still hot.

• Casting Machine

- We will conduct trials for new aluminum die-casting molds. - We can actually perform die-casting to check whether the product material is made according to the design specifications and whether it can be cast without defects in the material.

• Other Auto Parts

Large-sized aluminum die-cast products with a length of 600mm to 700mm can be produced.

Housei Industries has successfully formed undercuts using special molds and has been able to die-cast blind undercuts! While standard open-type undercuts can be formed using mold slides, blind undercuts cannot be formed this way. However, thanks to the special mold structure, it has become possible to form them. ● For more details, please contact us or download the catalog.

Gypsum casting is one of the casting methods that does not use metal, where molds are made from gypsum for casting. It is suitable for prototyping die-cast products and producing small quantities of die-cast level parts. 【Suitable for the following cases!】 ○ I want to create high-precision prototypes. ○ I want to produce die-cast level prototypes in a short time and with a quick turnaround. ○ I want to produce die-cast level parts in small quantities. ○ I want to create prototypes with design changes from existing die-cast products. ○ I want to carry out interim production until the die-cast main mold is completed. ○ I want to create thin-walled products. ○ I want to produce them at a low cost since machining is expensive. 【Features】 ○ Short delivery times. (If we receive 3D data, we can ship in as little as 7 days) ○ Low mold costs due to the use of simple molds. ○ Smooth casting surface comparable to die-casting due to gypsum molds. ○ High freedom in mold structure. → Supports undercut shapes. ○ Capable of producing thin-walled products at the same level as die-casting. → There are records of producing thin-walled products as thin as 0.5mm. ○ Iron-based materials can be inserted. ○ No need for draft angles. ● For more details, please contact us.

"Die casting" is a casting method in which molten aluminum alloy is injected at high speed and high pressure into a precision mold. Because the mold has a high cooling effect, it is possible to produce a large number of high-precision castings with excellent surface quality in a short time. 【Advantages of Die Casting】 ○ Productivity → Produces a large number of cast products in a short cycle of about one minute. ○ Dimensional Accuracy → High precision dimensional accuracy in the decimal range. ○ Thickness and Strength → High-strength products with thin walls around 1mm and tensile strength of 296MPa (sample data value). ○ Surface Treatment → Surface treatment for aesthetics and rust prevention when necessary. ○ Molds → Low wear, capable of producing around 100,000 products of the same quality level. 【Unique Strengths of Janome Die Casting】 ○ Capable of handling everything from prototypes to small and large lot production (skills honed by automotive manufacturers). ○ One of the few in Kansai with an 800t large casting machine. ○ Consistent support from casting to machining. ○ Maintains stable and high purity aluminum molten metal, ensuring stable quality. ○ Able to accommodate any project! ● For more details, please contact us or download the catalog.
