A typical Pro/ENGINEER software package is made up of different modules, customizable to the customer’s specific needs. Pro/ENGINEER is available in a pre-packaged set of scalable packages which include a broad range of 3D CAD, CAID, CAE, data management and other design related capabilities. […]
PTC was founded in 1985, by Samuel Peisakhovich Geisberg, who previously worked at Prime Computer, Computervision (CV) and Applicon. Pro/ENGINEER (a.k.a. Pro/E), the company's first product, shipped in 1988. John Deere became PTC's first customer. Once an initial version of Pro/ENGINEER was developed, the company received venture capital funding from Charles River Associates and Steve [...]
Pro/ENGINEER, PTC’s parametric, integrated 3D CAD/CAM/CAE solution, is used by discrete manufacturers for mechanical engineering, design and manufacturing. […]
The best solution to the problem of movement causing stress was very simple. If component A is forced against component B thus putting both components under stress, remove the stress. […]
Mold designers and builders try to use the typical methods of minimizing wear—such as using differential metals; using low-wear coatings; specifying high metal hardness thus equating high hardness with low wear; […]
Designing a product for high production tooling involves considerations that must be closely evaluated: gating location, part ejection, wall thickness, material flow characteristics, cycle time, hot runner feasibility and assembly at high rates. […]
The following guidelines should be considered:Resins UsedDepending on the emissions or gas residue given off during the molding process and flash point of the resin, the molder will have to evaluate whether to use 7- or 20-micron pore size. Resins such as ABS, polypropylene, soft type PVC, polyethylene, acrylic, polyurethane, […]
Gas permeable mold steel can be machined by conventional methods using cutoff saws, end mills, grinders, EDM, stoning, etc. It is important to remember that this material is honeycombed with thousands of microscopic holes, which are affected by metal removal. Oil coolant is recommended. […]
By using this venting material in appropriate areas, the molder can eliminate gas buildup, reduce injection pressure, lower cycle times, gloss levels and substantially reduce scrap and reject rates. […]
One such device that solves people’s problems is the ejector pin. Often considered a commodity, they are nonetheless critical to the successful function of a mold. The list of what can go wrong due to problems with them is endless. […]
