Children's toys are a very common inspection item, and there are many types of children's toys, such as plastic toys, plush toys, electronic toys, etc. For children, minor injuries may cause serious damage, so product quality must be strictly controlled
(1) Dent pits, mainly due to insufficient internal pressure in the mold, insufficient cooling, and different thicknesses of various parts of the finished product itself
(2) Insufficient short shot material feeding, mainly due to insufficient internal pressure of the injection molding machine and mold, insufficient material fluidity, poor air overflow in the mold, etc.
(3) Silver mark, mainly due to the vaporization and decomposition of moisture and volatile liquids in the material
(4) Deformation, mainly due to residual stress generated during product demoulding and insufficient cooling.
(5) Cracks are mainly caused by residual stress generated during product demoulding, assembly and handling, and inferior raw materials.
(6) White mark, mainly due to excessive load when the product is demoulded.
(7) Flow mark, mainly due to low mold temperature
(8) The gate remnant flash was not cleared, mainly because the workers did not perform corresponding inspections.
(9) Excessive or insufficient spraying of fuel
(10) Uneven spraying and oil accumulation
(11) Painting, oiling, scratching and peeling
(12) silk printing silk screen oil stains, insufficient cover bottom
(13) silk printing silk screen shift and dislocation
(14) plating turns yellow or black
(15) plating Yin and Yang color, rainbow spots
(16) plating scratches and peeling off
(17) Hardware accessories are rusted and oxidized
(18) Hardware accessories are poorly polished and have residue
(19) Stickers are warped or torn
(1) Holes, caused by: skipped stitches, broken threads, missing bottom/top seams, missing stitches, tattered fabric, and cutting the thread ends too deep.
(2) The plastic accessories are loose due to the following reasons: the plastic gasket is not pressed in place, the gasket is detached due to excessive heat, the pipe position nail is missing, the plastic gasket/paper is missing, and the plastic gasket is broken.
(3) The plastic parts are shifted/skewed. The reasons are: the plastic parts are placed at the wrong angle and the openings on the cutting pieces are incorrect.
(4) The reasons for uneven filling include: improper coordination of eyes, hands, and feet during filling, extrusion during production, and unsatisfactory post-processing.
(5) The product is deformed due to: the sewing pieces are not aligned with the marks, the sewing needle is not smooth, the operator's cloth feeding force is uneven during sewing, the filling cotton is uneven, the production process is squeezed, and the post-processing is inappropriate. .
(6) The seams at the sewing position are exposed. The reason is: when the cutting pieces are combined, the depth is not enough.
(7) The thread ends at the sewing position are not cut: the inspection is not careful, the thread ends are buried in the sewing position, and the reserved thread ends are too long.
(8) The filler is made of black cotton, etc.
(9) Embroidery leaks, thread breaks, errors
(1) The metal part is rusted and oxidized: the plating is too thin, contains corrosive substances, and the bottom layer is exposed due to damage.
(2) The spring in the battery box is tilted: the spring is poorly processed and is subject to external force collision.
(3) Intermittent malfunction: false or false soldering of electronic components.
(4) The sound is weak: the battery is low and the electronic components are aging.
(5) No function: components fall off, false soldering, and false soldering.
(6) There are small parts inside: parts fall off and welding slag.
(7) Loose components: screws are not tightened, buckles are damaged, and fasteners are missing.
(8) Sound error: IC chip error
