What is gate blush? Gate blush is a molding defects commonly caused at the gate location of injection molded part, It shows as rings or ripples in the mold cavity surrounding the gate area. This defect occurs when plastics material flow across the mold cavity rather than forming a fountain flow and freezing to the […]
What is Air Bubbles or Blisters defects Air Bubbles are molding defects that appear when gas is trapped in the melt material and injected into the cavity leaving a cosmetic defects in the plastic molding part, we also call this as gas traps issues or blisters defects. There some some reason to cause this Bubbles […]
What is Black Specks or Streaks Black or brown specks are spots of degraded plastic or dark spots that show on the injection molded part. This Black or brown specks defects will be more visible on white color or clear plastic molded parts, we also call as carbon buildup, sometime we normally think it is […]
MUD U Frame is A cost-effective approach to injection molding This MUD (Master Unit Die) Quick-Change systems was designed to reach the parallel challenges of increasing productivity and decreasing production costs. MUD Quick-Change U frame Systems are more frequently becoming a part of the operational strategies for many companies who employ lean mold manufacturing programs […]
Why need design ribs on the injection molded parts Injection molding technology is the most common manufacturing technology for producing high volume of plastics parts in the world. The purpose of these parts can range from a picture frame that is never touched to a gear that is used in a moving assembly every day. […]
Are you looking for different mold texturing surface finishs on a plastic part cavity side? Plastic parts not only benefit from designs that are pleasing to the eye, but they also benefit from the way a product feels when handled. Depending on the application, you may want your plastic mold part to be as smooth […]
Soft Mold Low Volume Plastic injection molding In line with the history of the branch, since 1999, completely different companies have been providing innovative soft mold low volume quantity injection moulding solutions to numerous high profile organizations throughout a variety of industries throughout all of the continents. Undoubtedly the addition of low volume injection moulding […]
How to avoid the Air Traps Defects As plastic fills the mold cavity, it compresses the air that is in the cavity. The pressure of the air pocket increases until the required pressure is achieved to push air out of the mold vents. If the areas where the air is trapped do not have a […]
How to save injection molding cost by Part thickness design reduction By do the DFM (Design For Manufacturing) report and mold flow analysis to keep part thickness down to the minimum but having the same strength, we have reduced cooling times by as much as 31 seconds! As you can see by the table below […]
Plastic Part Design Analysis Theory The plastic part molding process is heavily affected by factors of the plastic part design. If the critical parameters of a part design are not set correctly, the part will have quality issues during the molding process. The most critical of these parameters is as follows: Plastic Part wall thickness […]
How to prevent Sink Marks defects in advance Sink marks defects are localized depressions in the surface of injection molded parts caused by a non uniform shrinking of the plastic during the cooling process. In cosmetically critical parts, they can be a serious problem. Sink marks are dependent on part geometry and material shrink rates. […]
Mold Fill time is another name for melt front advancement. Our fill time animations provide the visualization of the part cavity filling before your very eyes! As you can see from the animation, phenomena such as race tracking, weld lines formation and air trap formation are easy to visualize. Race tracking is when the plastic […]
What is mold flow analysis report? Mold Flow Analysis (MFA) is a simulation tool that is used to predict and optimize the flow of plastic resin in a mold during the injection molding process. The simulation takes into account the properties of the resin and the geometry of the mold, and predicts the behavior of […]

We will discuss new inventions as well as active changes. Explore automation and robotics’ roles in change. Embrace the Union of Technology and Innovation. Discover the future. Stay tuned! What […]
Plastic Injection mold is what people call the process of filling liquid plastic into a mold and waiting for it to take shape. An injection mold maker is the machine that makes the mold for injection molding. An injection mold maker creates molds from metals, usually steel or aluminum. The process calls for precision because a mistake […]

Mold Cooling Channels (Water channels) is one of the important systems in plastic mold, Water Cooling lines plays the role in molding process that could improve distortion, tolerance, cycle time, sink mark, and so on, poor Cooling Channels will never able to got high quality molding parts. How a part cools has a dramatic effect […]
Brief summary difference between overmolding and 2k molding While injection overmolding and 2K injection molding (also known as 2-shot injection moulding) share many similarities, they also have some key differences. See below for the difference between those two moulding processes. Injection overmolding involves the use of a standard single-nozzle injection machine to combine two distinct […]
Stack Molding: Everything You Should Know Stack molding is an outright revolution within the injection molding industry because it boosts production speed. In stack molds, at least two or more compacted cavities mean that different parts are molded in one go to increase efficiency. But for now, what is stack molding, and how does it […]
