Wall thickness could be measured by parts cross section. Depending on part design, a single part could have many different wall thicknesses. For injection molding part, there are some suggestion regarding wall thickness for a better surface finish and easier production. Too much wall thickness Plastic expends when temperature goes up and shrinks when temperature… Continue reading
B-2-Tolerance
Plastic parts will never be the 100% same as the CAD design, since part geometry, material characteristics (raw material expands and contracts according to thermal difference), mold construction (CNC machining), processing variability…etc. Therefore, to indicate the area of the part that shall follow the CAD design and the allowed difference is very important. The allowed… Continue reading
B-1-Design Preparation
There are many ways to produce products, why choose “plastic injection molding” ?? I see 3 reasons below after comparing several manufacturing processes: Here are some principles (not limited) I will consider during design stage if we decide to produce a part with plastic injection molding process, many factors affect plastic-part design. Among these factors… Continue reading
A-5-Exhibition Preparation
Participate in exhibition is a very interesting experience, it gave me chances to traveled to many countries, meet different people, food ,and culture. Exhibition is an assembly at particular time and place by people who are in common in particular aspect, it is a chance for participants to know each other and get very much… Continue reading
A-4-Supplier Management
An automotive consisted of thousands of parts such as engine, transmission system, steel frame, and many plastic parts……etc. These parts could not be manufactured by a single company, but hundreds of suppliers. If a party generates trouble, everybody would be in trouble, good supplier management is really mattering to the project and industry. The major… Continue reading
A-1-Delivery Tracking
An accomplishment of product generally needs 3 parties in the industry: Timeline is one of the key elements we check weekly, since there are always some troubles happen to affect the delivery schedule. Delays from key suppliers for steel, components, hot runner systems and mold bases, machining and assembly, trial shot and shipment could be… Continue reading
