For some of small volume 2 color injection molding parts, use two shot injection molding process will be more high cost since the machine cost is very high, to solve this issue with traditional injection molding maching, use overmolding process will be one of the best options for low volume parts, but how to define the volume of 2 color parts, you can refer to overmolding product page to know more about this.
Design considerations for high volume injection molding
Several considerations must be considered while developing a plastic product for high-volume injection molding.
First, the wall thickness should be uniform to ensure that the cooling process does not cause the item to deform. Thin walls are excellent for mass production since they take less material and time than thick-walled sections, which provide additional strength where needed.
This is also true for part size and shape, which determine production time. Larger or more intricate shapes may necessitate longer cycles or specialist equipment, increasing costs. The more intricate the design, the more difficult it is to produce in large quantities; thus, geometric designs are chosen. Draft angles should also be included in the design to allow for simple removal of the parts and to avoid issues like cracking or distortion during production.
The position and size of gates are critical. Gates should be positioned so that they do not jeopardize the building’s structural integrity, and they should be of the appropriate size so that they do not obstruct the flow of materials being moved. Material selection should consider the part’s strength, durability, and flexibility.
It is also important to consider the surface finish. Parts’ surfaces should be polished and free of imperfections like warping or sink marks. Proper gate placement, mold design, and material selection are among the aspects that contribute to achieving a smooth surface. Finally, tolerance, or the permitted variance in the dimensions of the parts, should be taken into account from the start of the design process to ensure that the parts are manufactured accurately and with a high level of precision.
Common defects in high volume injection molding
Several types of defects can occur during high volume injection molding, affecting the quality of the end product. Sink marks are created as a result of uneven material distribution during the cooling process and can be prevented by redesigning the part and maintaining consistent wall thickness. Distortion, which causes part distortion, can be avoided by controlling the mold’s temperature and incorporating stress-reduction measures.
Flash excess material that protrudes from mold joints is caused by misalignment or a lack of clamping force and may be avoided by properly aligning the mold and applying sufficient clamping pressure. Short shots and incomplete filling of the mold cavity caused by issues such as low injection pressure or clogged gates can be resolved by modifying the injection parameters and gate layout.
Finally, weld lines, which are visible indicators of meeting flow fronts, should be avoided by properly designing the mold and injection parameters to guarantee equal material distribution. These tactics help to ensure that the high volume injection molding produces high-quality products.
Tips to Increase the Productivity of High-Volume Injection Molding
Problem solving is critical in high volume injection molding to assure the quality of the finished product. Here are some practical methods for dealing with typical challenges.
Check Machine Settings: Start the problem-solving process by checking the injection molding machine specifications. Ensure that the temperature, pressure, and cycle time are correctly set according on the material to be treated.
Address Material Flow Problems: Pay particular attention to any problems that may occur in the realm of material flow. Defective settings of the machinery or the existence of impediments in the flow of materials might also be a hindrance. Make sure the material does not get stuck in the machine during the procedure.
Combat Warping and Shrinkage: Distortion and shrinkage are common problems in large-volume injection molding due to uneven cooling. Reduce the cooling time based on the material qualities to avoid warping and shrinkage of the part.
Prevent Air Traps: When air becomes trapped in the mold cavity, it forms voids or bubbles. Check the mold for any trapped air pockets that could affect the final product.
watch the Process: Make sure you closely watch the entire injection molding process. The following are some of the best practices for detecting problems early: This proactive approach allows one to avoid potential issues that may affect product quality.
