Troubleshooting Short Shots
Short shots are a common issue in injection molding. They happen when the molten plastic doesn’t fill the mold cavity fully. This results in parts that are incomplete or too small. It’s important to fix short shots to keep the quality of injection molding high and meet production goals.
Potential Causes and Solutions
There are many reasons why short shots occur in the injection molding process step by step. Let’s look at some causes and how to fix them:
- Restricted flow areas: Things like mold design issues or problems with the melt delivery system can block the plastic’s flow. Make sure the mold is designed well and the flow channels are clear to help fill the mold better.
- Insufficient melt or mold temperature: If the molding cycle temperatures are low, the plastic might not flow enough to fill the mold. Adjust the injection unit and cooling system temperatures to get the right balance.
- Inadequate ventilation: Air trapped in the mold can stop the plastic from filling it fully. Make sure the mold is well-vented to let air out during part ejection.
- Machine malfunctions: Problems with the clamping unit or other machine parts can cause issues with resin drying and melt delivery, leading to short shots. Keep the machine in good shape and fix any problems quickly.
By finding and fixing the causes of short shots, you can make the injection molding process step by step better. This helps you make high-quality parts that your customers will like.
Addressing Flash Issues
Flash is a common problem in plastic injection molding. It happens when molten plastic gets out of the mold through gaps. This can be due to low clamping force, mold gaps, or wrong process settings. THY Precision is here to help you fix this issue.
The injection molding process has many steps to follow for success. Finding and fixing flash problems is key. THY Precision’s experts are skilled in solving flash issues. They will help you through the process.
Potential Causes and Solutions for Flash
- Low clamping force: Increase the clamping force to prevent the mold from opening and allowing the plastic to escape.
- Gaps in the mold: Inspect the mold for any gaps or imperfections in the parting line and address them through mold design improvements or maintenance.
- Improper injection parameters: Optimize the injection pressure, speed, and other process settings to ensure the plastic is contained within the mold cavity.
- Worn or damaged mold components: Replace any worn or damaged mold components, such as ejector pins or guide posts, to maintain a tight seal.
- Excessive resin drying: Ensure that the plastic resin is properly dried before injection to prevent excessive melt fluidity.
By fixing these issues, THY Precision can help you get rid of flash and make high-quality products. Our team is ready to guide you through the process. We use our knowledge and top solutions to help you succeed.

Eliminating Voids, Bubbles, and Sink Marks
In plastic injection molding, voids, bubbles, and sink marks are big problems. They can hurt the strength and look of your products. These issues happen when the plastic cools and solidifies. Knowing why they happen helps us fix them.
Not enough packing pressure is often the main reason for voids and bubbles. This can trap air, making your parts look bad. To fix this, work on your melt delivery system and clamping unit for better packing pressure.
Sink marks come from plastic shrinking as it cools. This can make depressions on the part’s surface. To avoid this, try changing your cooling system. Adding cooling channels or raising the mold temperature can help.
The design of your mold also affects these issues. Think about where the gate is, how thick the part is, and how the melt flows. This can help you avoid defects in the molding process.
Fixing these problems means looking at the root causes and solving them step by step. This way, you can make high-quality plastic parts without defects. Understanding the molding process and always trying to improve is key to success.
