Design engineers don’t have to be fluid dynamics experts to injection mold plastic parts without a hitch. The following rules will help engineers avoid problems when designing injection-molded plastic parts: Rule 1: Keep Wall Thickness Consistent Plastic part walls must be uniform in thickness. This is the most basic design parameter, and strict adherence to [...]
Blow molds are used to produce many items that we use every day, such as drinking bottles (food and beverage industry), perfume bottles (cosmetic industry), bottles and containers for medicines (pharmaceutical industry), or bottles and containers for creams or other care products (household and care industries). The various materials used for the final products require [...]
There are all kinds of approaches to sales and marketing. They all help to some extent, but they also leave much to be desired. What’s worse is that your customers are often more focused on sourcing the cheapest molds instead of maximizing their own throughput. It seems like some customers only care about the price [...]
Mold flow simulation is a crucial part of engineering and producing molded plastics for a range of purposes. Molded products requiring custom injection should always have a simulation done before producing a prototype, as this increases the chances of a successful product. With advances in technology, the in-house engineering team of a molded plastic manufacturer [...]
Friends, if you look around you, you will see that you are surrounded by things made of plastic, and every day you buy some items in which plastic has been used. This means that the consumption of plastic is very high and it is increasing day by day. Suppose plastic is harmful to the environment [...]
The reasons for a high-gloss finish in plastic molding vary. Some examples include extreme transparency of the molded part, reduced localized corrosion or highly crack-sensitive tooling (due to design or operational stresses). Then there is the impact of mold surface finish on injection molding productivity, as the release forces of the plastic part from the [...]
Venting molds is extremely challenging because you must create a gap in the molding surface large enough for the gas to escape, but small enough so plastic does not leak out. A very fine line exists between gas traps and flash, and not crossing this line is a constant balance. As molds get more complex, [...]
The mold manufacturing industry is constantly evolving. As a result, options for overcoming complex mold texturing challenges are evolving, too. Our complex marketplace demands new and innovative design possibilities with higher accuracy and tighter tolerances while keeping production times as short as possible. For example, some projects may require depth or detail unachievable by acid [...]
Insert molding is when an insert typically made of metal is placed in the cavity prior to plastic molding around it, bonding with the insert to make one final product. Overmolding is quite similar, although the initial substrate is molded first, then, plastic is molded around it to create a two-shot final product. There are [...]
Automotive headlight housings have evolved from round, stamped steel assemblies to thermoset parabolic reflectors with diamond-like angles, covered with clear lenses. Today‘s BMC (bulk molding compound) reflectors are cosmetic parts with complex curves and shapes. Their parabolic surfaces are the aiming mechanisms for the light. With the move to clear lenses, any imperfections in the [...]
