Plastic injection molding can apply a specific type of finish — described in terms of polish or texture — to molded parts, and many different polishes and textures can be achieved. The desired surface finish is applied toward the end of the mold-making process, and during plastic injection molding, the finish is transferred from the […]

Sink marks are unwanted depressions, or dimples, on the surface of an injection molded part. Generally, these defects do not affect the part’s strength or function; however, designers and injection molders still want to avoid cosmetic blemishes. Proper part design can help, but the design of the mold and the skill of the injection molder […]

In 2023 Chinese New Year, also known as the Lunar New Year, comes early—starting January 21st. Here’s what you need to know. Key Takeaways Chinese New Year creates a period of downtime for overseas manufacturers from January 18th – January 29th 2023. We recommend placing international orders within the next few weeks to avoid that […]

Weld lines in injection molding are a type of cosmetic defect that detracts from a plastic part’s appearance. In some cases, a weld line can also cause a loss of strength and impact resistance. Known also as knit lines and weld marks, weld lines are difficult to eliminate completely, especially if your injection molded part […]

Overmolding in injection molding is a process that combines multiple materials together to form one single part. Typically, the first material (the substrate) is covered partially or fully by a second material (the overmold). The two most common applications for overmolding are: Combining threaded metal inserts with a plastic part  Combining a harder plastic with […]

The Mid-Autumn Festival is widely celebrated throughout Asia and is fast approaching. The festival is held on the 15th day of the 8th month of the lunar calendar when the moon is full and celebrates the end of the autumn harvest — it’s similar to Thanksgiving in the US. In 2022, the festival falls on […]

For any engineering project, countless hours go into 3D modeling, prototyping, and refining the design. Often, the final step is to prepare your designs for the injection molding process, but where do you start? How long will it take to go from the initial part designs to your first molded parts? This is a long […]

Oftentimes engineers and product designers place much focus on selecting the appropriate grade of plastic when developing injection molding part designs. Equally important, though frequently an afterthought, are the metal materials used to manufacture the injection molding tool itself.   There are multiple commonly used grades of metals for tooling, and they’re typically used for the […]
