Hello! I'm Zhanghuimin. I speak for TPE!
As a professional salesman of elastomer TPE/TPR/TPU / TPEE rubber materials! A salesman who doesn't know his product is not a good salesman. To fully express my professionalism, I will organize more information about TPE/TPR/TPU / TPEE materials to share with you! TPE coated ABS material is currently a very mature product for the industry, but occasionally there are still some customer styles that do not achieve his desired results. It is the TPE material that has problems or the forming process is not appropriate. If you are looking for materials purchased by a professional TPE salesman, then you can rule out the phenomenon of TPE buying wrong. When purchasing TPE coated ABS materials, please consult the TPE supplier for the molding parameters and precautions. So today we make the following analysis on the problem of the viscosity of TPE coated ABS materials, and follow my footsteps to see ...
1: When TPE is coated with ABS material, how is the deformation of ABS components formed?
Improved countermeasures: high forming temperature; Injection pressure(overpressure). Improvement countermeasures: mold to do stiffening tendons; Adjust the position of the inlet; Adjust TPR and TPE materials to appropriately reduce the coating forming temperature; Lower the holding pressure and lower the rate of fire.
2: TPE adhesive insecurity reasons: material problems; The forming temperature is low.
Improvement countermeasures: Select the special brand of plastic ABS; Improve the coating forming temperature appropriately.
3: The reason why TPE is not demoulding when it is coated:
Improvement countermeasures: die product structure; Material problem. Improvement measures: modification of die structure(surface treatment, drawing die angle, inlay top out); Adjust the material, look for good demoulding TPE brand; Demolant.
4: TPE coated ABS into the rubber layer reason:
Improvement countermeasures: TPR, TPE material sub-compatibility is not good enough; Injection is too fast. Improvement countermeasures: improve the compatibility of TPE mixing system; Reduce injection speed appropriately.
5: TPE coated product surface watermark surface, the cause of poor luster:
Improvement countermeasure: the reason glue contains moisture; The forming temperature is low. Improvement countermeasures: baking materials; Improve the coating forming temperature appropriately.
6: The reason for the gas pattern of plastic products: the forming temperature is too high; Mold exhaust is not good.
Improved countermeasures: appropriate reduction of forming temperature, appropriate reduction of firing rate, or modification of the mold, so that gas discharge.
7: TPE coated ABS products placed a month or two after the surface whitening or sticky reasons: TPR, TPE adhesive additives in the amount of excessive, long-term migration and precipitation, infiltration to the surface of the material.
Improved countermeasures: For products that have problems, there is basically no good post-treatment method. It is recommended to start with the source raw materials. At present, such problems are not uncommon in ABS coated products. However, for this type of quality problem, the market has developed ABS packaging materials that are not precipitated.
To sum up the above, the common problems of TPE coated ABS materials are collated and analyzed. If the above problem points do not help you, or if you do not give a corresponding explanation of the problems encountered, you can call us. We will explain to you one-on-one, convenient time we can arrange materials engineers for you on the spot style, free of charge technical support!
