takao injection mold engineering co ltd load analysis and strength simulation i am afraid that losecon®-30 pat looks fragile especially because of its thin shaft obtaining specific values of allowance

losecon®-30 pat because it is structurally and conceptually different from the conventional construction takao injection mold engineering co ltd engineered study we offer our unique technical service without charge in order even for first customers to use our products with a feeling of security please feel free to contact us if you have a concrete theme please also send us the sectional drawing that includes losecon®-30 pat integrated part and the plan view that tells us the product shape by fax or send us 2-d data dxf iges dwg or fda of them joint 30 rature 20 ingtempe slim design is feasible because bending moment is not generated on the core rod-bar the loose core is compact in size interference to ribs and restriction on the shape are eliminated a circuit that promotes the temperature control effect can be designed whole circumference 0.2 0.3 ris average thermal n expansio large inclination angle is settable molding machines can be downsized because of reduction in thickness loose engagement is provided on each joint with consideration of machining allowance and heat expansion no strict precision is required for mold production ejection is performed with a safe
