TOOLINGS FOR OPTIMAL PERFORMANCE AND RELIABILITY The core of the injection molding process is the tooling. In regard to their design and manufacture, the high-end machinery used is absolutely essential. This is why Yomura introduced a state-of-the-art and fully-automated system works 24/7 to fabricate the toolings and makes no compromises with respect to quality – and conceives and produces high-precision, custom made fast cycling injection toolings in house.   MANUFACTURING CAPABILITY Tooling Automatic Fabrication Key points: All Process and measurement data are connected to minimize men key in error. All work piece are implanted with RFID chip to minimize men error.  Pre-set 2D and 3D are used before and after process to ensure the work piece are manufactured to the 100% accuracy.  Productivity will be expected to increased at least 30 % monthly.

LIQUID INJECTION MOLDING

Categories : Silicone Injection Molding Machines

Liquid Injection Molding (LIM) and Transfer Molding are preferred processes for manufacturing solid silicone rubber items used in a wide range of applications such as medical equipment, watersports, gas masks, military gear, waterproof device cases, 3C products and much more. MATERIALS: Shin Etsu / Dow Corning/ GE Silicones ADVANTAGES & APPLICATIONS: Low viscosity and lower injection pressure, good for silicon molding Good chemical stability and environmental protection High dimensional accuracy It produces high quality parts without secondary finishing and allows much shorter production cycles than other processes. Over-molding together with hard plastic frame (PC or ABS etc.) for waterproof devices, shock proofing, shielding, etc. Very thin wall design (0.25mm thick around) for silicone to adhere on plastic housing (rib) to meet the demand of low profile product design. Water proof feature can be secured by the combination of soft rubber contacts and with constant pressure provided by hard plastic housing (rib).

MICRO MOLDING

Categories : Injection Molds

Micro molding is a very specialized art form, which is a kind of tooling design , manufactures small and precision plastic components with polymer-based functional devices, by increasingly demanded in the fields of life science, electronics, medical, photonics, automotive, and aerospace. The tiny-scale molding form of injection molding that entails building a cavity to match the shape of the part you want to make, sort of like the plastic molding that makes Lego bricks. THERE ARE THREE DIFFERENT THINGS TO KEEP IN MIND WITH MICRO MOLDING : Micro means the size of the part. It is the most common definition when dealing with micro molding. Micro features relates to tiny parts on a larger part. As a whole, the part can be big, but its components can be smaller, or micro features. Micro tolerance is how the parts are measured and how close to the needed measurement the part has to be to be considered a good or usable part. When a part is molded, it has to measure within the needed measurement (the tolerance), which could be as small as a thousandth of an inch. Small parts that are simple to make have tolerances that are not as tight and would be considered regular molding. SOME ADVANTAGES OF DESIGN GUIDE IN YOMURA AS : Dimension Aspect ratios around 6:1 (material dependent) Wall thickness : 0.3 mm ( 0.012”) min. for plastic Hole dimension : 0.2mm ( 0.008”) – 0.5mm ( 0.02”) min.  Pitch of hole      : 0.3 mm ( 0.012”) – 0.50 mm ( 0.02”) min.  Tolerance (min) : 0.01 mm ( 0.0004”) – 0.02 mm ( 0.0008”).

The machine is designed for silicone rubber products which have poor fluidity and require long heating time.

IN MOLD DECORATION

Categories : In Mold Labeling Injection Molding Machines

In Mold Decoration (IMD) is a cost effective method of decorating plastic parts. It consists of four steps: Printing, Forming, Trimming and Injection Molding. After a plastic film is silk screen printed with a customer’s design, it is then thermo-formed over a soft tooled mold. Once the plastic decoration is shaped it is trimmed to size. After trimming, the shaped film is placed into an injection mold and a selected mold material is injected behind it forming an integrated bond. IMD offers long lasting decoration with multiple colors and textures. Beyond IMD, membrane switches and/or additional double injection molding can be added to your part or product for extended functionality.
