Problem: Work Week calendar on Outlook is 1 week advance from Semiconductor Work Week

Direction on how to adjust on Outlooks Calendar:

1) On Outlook, click Tools then click Option.

2) Under Preferences, click Calendar options.

3) Once the Calendar Options Window opens, change the First week of year to First Full Week. Click Ok, then Ok again.

SolidWorks Standard

SolidWorks Standard has most of the functionalities of part and assembly modeling (such as 3D solid modeling, advanced surfacing, sheet metal, mold design, direct model modification, etc.), 2D drawings (such as dimensioning, annotation, international standards support, drawing compare, etc.), design reuse and validation (such as SolidWorks search, design automation, configurations, design library, 3D models from suppliers, etc.), animations and renderings (such as assembly animation and walk-through/fly-through animations), design validation and simulation (such as collision and interference detection, hole alignment checks, check manufacturability, fluid flow simulation, sustainability, and draft and undercut analysis), and collaborating and sharing (such as import/export, 3D for rapid prototyping, eDrawings, etc.). Some functionality was recently added to SolidWorks Standard 2011 such as the appearance functionalities (controls in PhotoView or PhotoWorks) and decals.

SolidWorks Professional

SolidWorks Professional has all the capabilities of SolidWorks Standard and additional functionalities such as standards checking for 2D drawings, standard component library and task scheduler for design reuse and validation, and eDrawings Professional for collaborating and sharing.

SolidWorks Premium

SolidWorks Premium has the capabilities of SolidWorks Professional plus additional features such as piping/tubing design and electrical cable/harness design for part and assembly modeling; flattened harness drawings for 2D drawings; tolerance and stack-up analysis, kinematic motion simulation, and structural validation for design validation and simulation; and importing scanned data for collaborating and sharing. Both SolidWorks Professional and SolidWorks Premium now have PhotoView 360 which serves as SolidWorks standard photorealistic rendering solution.

SolidWorks 2011 Enhancements

For SolidWorks 2011, there have been enhancements in assemblies (ex: fillets and chamfers), drawings and detailing (ex: dual unit support), enterprise PDM (ex: enterprise PDM menus), model display (ex: DisplayManager), parts and features (ex: defeature for parts), simulation (ex: new 2D simplification study), and weldments (ex: weld beads).

Injection Molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Plastic is known to be versatile and economical material that is used in many applications.

Products will be designed by industrial engineers and or an engineer. In modern age, the product can be designed using Computer aided design such as Solidworks, AutoCadd, Pro-E and many CAD softwares.

Design consideration

Always minimize undercut to minimize manufacturing cost. Can use slider if undercut is unavoidable due to its special feature.

Draft. Part design should include draft features to facilitate removal from the mold in direction of the mold opening . Typical draft angles should be 1 to 2 degrees for part surfaces.

Wall Thickness. Use uniform wall thickness throughout the part. This will minimize sinking, warping, residual stresses and improve mold fill and cycle times.

Radii, Fillets and Corners. External and Internal radii should share same center point. A fillet radius should be 25 to 60% of nominal thickness. Break all corners with radius. Suggested minimum radius is 0.5mm (0.020in).

Ribs. Rib thickness should be 50 to 60% of the nominal wall thickness and the maximum height is 3 times the height of the wall.

Boss and Gussets. Typical OD of boss is 2 times ID. It’s height should be less than the 3 times of OD. The height of Gusset can be up to 95% of the boss. While it’s length can be 30 to 100% of its height.
