Stress Relief Toy Dumbbell Stress Balls Features:
1. The hardness of the product can be adjusted according to requirements, and the weight of the product can also be adjusted within the upper and lower ranges according to customer requirements. The quotation is only for conventional hardness and weight. The soft and soft feel of the product can be adjusted according to customer requirements. No additional charges are required.
2.PU slow rebound products and rigid foam products, due to different materials and process changes, the unit price must be calculated immediately.
3.PU foam toy gifts have many inherent disadvantages or defects due to process limitations.
First, the thickness of the clamping line cannot be all the same: PU foam products are made by in-mold injection through heat setting and subsequent processing steps. During in-mold injection, the size of the clamping line is very large compared to the mold. The mold blank is hand-made, so there are many human factors, so it is difficult to make the thickness of the mold line completely consistent in the injection molding.
Second, the weight cannot be completely consistent: This is related to the mold clamping line discussed in the first point, because the thickness of the clamping line is inconsistent, the residual material out of the mold is inconsistent, causing the actual finished product weight to be inconsistent. In addition, the injection molding machine The accuracy has a lot to do with it. Any device has a precision issue. In general, like an ordinary 20g product, plus or minus one gram is normal.
Third, the touch is not completely consistent: as mentioned in the second point, the weight is inconsistent, of course, there is a small gap in the touch
Fourth, the overall level of trimming is inconsistent: the burr that is cast is manually trimmed, due to the inconsistency of everyone's methods, causing small differences.
Fifth, the LOGO position of the heat transfer sticker process cannot be exactly the same: for some complex LOGO, the sticker process must be adopted. The stickers (TRANSFER STICKER) are manually aligned, so it is impossible for everyone to make a complete uniform.
Sixth, the biggest defect is the defect in product modeling: because the product is foamed, it is a blank that is molded at one time, so there must be a certain degree of radian when it is too sharp. And ca n’t be separated, for example, car tires and body must be connected together
