Fabrication of Parts Containing Small Features using Stereolithography
The StereoLithography (SL) process has benefited from many advances in the last four to five years. These include new resins with reduced shrinkage and curl distortion, enhanced software, and improved scanning techniques. One can produce highly accurate parts for most dimensions within a few mils of the design value as shown in numerous accuracy and benchmarking studies. SLA systems use a laser...
متن کاملProductivity and Accuracy in Plastic Injection Mould Quotation
The quotation in the field of injection mould tool manufacturing is still so difficult mission and means so great challenge that leads the manufacturers be more bottleneck providing huge differences between the results of cost and time calculation following hand-rules or experiments. The simple cause of this is the very fact they must estimate the mould’s design and manufacturing time and cost ...
متن کاملImprovement of Soft Tooling Process Through Particle Reinforcement with Polyurethane Mould
Use of conventional flexible polymeric mould materials yields to longer solidification time of (wax/plastic) patterns in soft tooling process, thereby reducing the rapidity of the process to a great extent, which is not desirable in present competitive market. In this work, approach of particle-reinforcement with mould materials is introduced to reduce the cycle time of Soft tooling process and...
متن کاملDirect Injection Molding Tooling Inserts from the SLS Process with Copper Polyamide
The "RapidTool" Short Run (SR) Tooling Process using the Copper Polyamide material provides a route to mold inserts for injection molding made directly in the Selective Laser Sintering machine. The STL files for the mold inserts are shelled and conformal cooling lines and ejector pin guides are added before SLS processing. Sintering of the material in the SLS machine provides quick metal/plasti...
متن کاملXiv. the Rancidity of Coconut Oil Produced by Mould
IT is now generally agreed that the deterioration of oils and fats, whether due to the action of air, light and moisture, or to the action of micro-organisms, is an oxidative process subsequent to partial hydrolysis. In these two forms of rancidity-that of pure fats (where the absence of nidus prevents bacterial or mould growth) and that caused by micro-organisms-the course of the oxidation is ...
