how to design snap latches
Snaps allow an easy method of assembly and disassembly of plastic parts. Snaps consist of a cantilever beam with a bump that deflects and snaps into a groove or a slot in the mating part. Snaps can have a uniform cross-section or a tapered cross section (with decreasing section height). The tapered cross-section results in [...]
The typical inserts in plastic parts
Inserts are used in plastic parts, to allow the use of fasteners such as machine screws. The advantage of this is that since these inserts are made out of metal, they are robust. Further, machine threads also allow great many cycles of assembly and disassembly, Inserts are installed using one of the following methods. [...]

Introduction to plastic molding
Plastics are synthetically produced non-metallic compounds. It can be molded into various forms and hardened for commercial use. Plastic molding products can be seen everywhere. Examples are jars, protective caps, plastic tubes, grips, toys, bottles, cases, accessories, kitchen utensils and a lot more. Even the keyboard and the mouse that you use are made through [...]
Introduction to Die Casting
Die casting is a process that produces metal parts by forcing molten metal into reusable steel molds under high pressure. These molds also known as dies are specially designed to produce different shapes of varying complexity with a high level of accuracy and repeatability. […]
Typical Complications of Injection Molding
1) Incomplete Fillings: a) not enough resin to fill the mold completely b) inadequate injection stroke c) low injection rate d) low injection pressure e) resin viscosity too high f) exotic geometry […]
how to design a reasonable Living Hinge in plastic product
Living hinges are thin sections of plastic that connect two segments of a part to keep them together and allow the part to be opened and closed. Typically these are used in containers that are used in high volume applications such as toolboxes, fish tackle boxes, CD boxes etc. […]
how to make texture and lettering in plastic part
1) Textures and Lettering can be molded on the surfaces, as an aesthetic aid or for incorporating identifying information, either for end users or factory. Texturing also helps hide surface defects such as knit lines, and other surface imperfections. The depth of texture or letters is somewhat limited, and extra draft needs to be provided [...]
