Undesirable phenomenon: 1. Bubbles inside the product, NG for light guide (as shown below). 2. Deformation of the elastic reset buckle of the product (as shown below). Reason: Due to the long packing pressure of 11×11×11 during molding, the PC material has poor fluidity. The design diameter of the main channel ∅4 affects the fluidity […]
Function: drive thermal induction roll paper thermal printing. Undesirable phenomenon: flow marks on the surface of the product, runout degree 0.1mm, actual measurement: 0.22mm, judge NG. Reason: The product uses POM material. The melting temperature of POM is close to the decomposition temperature, and the moldability is poor. When the material flows to the position […]
Material: PP + E / P-TD20. Undesirable phenomenon: oil accumulates on the parting line after the product is sprayed, and the appearance is judged to be NG. Reason: There is a mismatch in the parting position of the product, and the mismatch is 0.05mm. Due to the corresponding injection in the rear stage of the […]
