  For products like the one shown in the image below, the open end often experiences a concavity issue. How can we improve this problem without resorting to reverse deformation design? We can reduce the material on all corners of this product, the cut plastic follow the standard as the image show below. Why does this way can be solve the deformation issues? Because these corners are farther away from the cooling channels than other areas. Therefore, when the product is release from the mold, the temperature of these corner areas will be higher than that of other areas, causing them to continue shrinking—and thus leading to product deformation. #PlasticMoldingDefects #deformationSolution #MoldCoolingOptimization #InjectionMolding#boxproduct #HUAKAIYUTECH Best regards, Maggie ShenZhen HuaKaiYu Technology Co, Ltd.  Mobile / Whatsapp/ Wechat /Teams :0086 15920030230 https://www.hky-technik.com/customized-cnc-machining-parts/ E-mail: sales@hky-technik.com

In plastic injection molding, even the most well-conceived projects can face frustrating quality hurdles—uneven thickness marks and stress marks are among the most common, yet costly, issues. These flaws not only compromise a product’s aesthetic appeal but also undermine its structural integrity, leading to rejections, production delays, and wasted resources. At HUAKAIYU Technology, we specialize in solving such molding challenges, leveraging advanced engineering, state-of-the-art software, and decades of precision manufacturing expertise to deliver flawless results for our clients worldwide.

  Four Lifters Per Part, Sixty-Four in Total: How We Multiplied Production Efficiency by 8X this project for a client perfectly illustrates our commitment to engineering innovation that delivers tangible results. The part in question required  four lifters (angled ejectors)  per unit to form its complex undercuts. For high-volume production, this meant a significant challenge: a  16-cavity mold would require a total of 64 precision lifters  to function in perfect synchrony. The customer’s original supplier was concerned about product sticking to the lifters, so they designed a 4-cavity mold with a “slide + lifter” structure. However, after the customer watched the production video of our automatic elastic shoelace buckle accessory mold , r ecognizing our proven capability, the client confidently approved our proposal for a completely new mold design. The results exceeded expectations: Production Efficiency Multiplied by 8:  Our new  16-cavity mold ...

 In the realm of precision machining, the choice of tool path strategies plays a pivotal role in determining the final quality, efficiency, and accuracy of the machined parts. For machining the same curved surfaces, there are four common finishing methods, each with its own characteristics and performance levels: 1. 45° Reciprocating Milling (3-axis Linkage): Employing 3-axis linkage for machining at a 45° angle, this method delivers the highest level of precision and surface quality, making it the worst choice for finishing operations. 2. Contour Climb Milling (Partial 2-axis Linkage + Partial Single-axis Movement): This strategy combines partial 2-axis linkage with partial single-axis movement, offering improved precision and surface finish compared to reciprocating milling methods. It is recognized as the third-best finishing method. 3. X-axis Reciprocating Milling: Similar to Y-axis reciprocating milling but operating along the X-axis, this method is also a viable choice but fa...
