 Uneven thickness marks, and stress marks, how to resolve these issues by injection molding process. 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. Plastic martial : PC/ABS  cavity number: 2 Please the images bloew, we can solve the Uneven thickness marks(stress marks) by the injection molding process parameters, so if your plastic part has these issues, you can  shipping your mold to us, or give a chance to us to do this ki...

 How to quickly evaluate product surface shrinkage using 3D software UGNX: 1,   Select the check wall thickness command: the part normal thickness is 2.56mm you can move you mouse to the reddest areas to measure the largest thickness, but if you Change the part display mode to wireframe, you can see a ball,  this is the software creating that this area can be built largest ball into this. then  how do we determine whether this areas will show sink marks?   ∅E ≤ 1.18A. If this area is close to the gate, the meaning the flow length ratio is relatively small, this ∅E value can be further increased. 2.56mm*1.18=3.02mm<3.10mm  so we can think this areas will be show a bit sink mark. #sink #mark #injection #molding #defect, #plastic #part #cosmetic #defect, #design #plastic #product #standard, #DFM, #technique Best regards, Maggie ShenZhen HuaKaiYu Technology Co, Ltd.  Mobile / Whatsapp/ Wechat /Teams :0086 15920030230 https://www.hky-technik.co...

Metal Injection Molding (MIM) is an advanced manufacturing process that merges the design flexibility of plastic injection molding with the material performance of powder metallurgy. It is particularly suitable for producing high-volume, complex, and precision metal components. Based on the MIM material properties data from  ElementPlus , this article provides an overview of several key MIM material categories—highlighting their compositions, characteristics, and potential applications—to assist engineers, purchasers, and product designers in material selection. 1. Stainless Steels Stainless steels are among the most widely used MIM materials, offering a balance of corrosion resistance, strength, and surface finish. MIM-316L : Compliant with MPIF 35, this low-carbon variant (C ≤ 0.03%) provides excellent corrosion resistance (≥ 96 h) and high elongation (≥ 50%). Ideal for medical devices, food processing equipment, and marine applications. Typical composition after Sintering Charac...
