After the product factory, every year will receive a variety of customer quality problems, causing customers to complain, to both sides of the formation of losses.-How to identify good and bad glass bottles-good and bad glass bottles
Return to Zan cause: mainly in the process of quality control in the formation of improper, now on the process of quality control to make some brief comments.-How to identify good and bad glass bottles-good and bad glass bottles

Mould inspection:

Must be in the opening of the mould instant communication with the customer, consultation, the key dimensions of the amendment to reach a consensus on the subsequent product yield and the effect of forming a critical impact.

all moulds in the factory must be the mouth of the mould, the initial mould, into the mould to stop supporting, according to the drawings or customer requests to stop the test.-good and bad glass bottles

Second, pieces of inspection:

Bottles from the front line just out, by the quality control team leader will be each into the mould out of the product limit 2-3, according to the drawings of the whole aspect of the stop test, is in addition to the above, another need for capacity measurement, the weight of the material measurement, the mouth of the internal and external diameter.

If necessary, Jiang bottle filled with water, with the customer’s cap for physical assembly to test whether the cap can be put in place, whether the water leakage. And make internal pressure, internal stress, acid and alkali resistance test.

Process Inspection

Without changing the mould condition, every 2 hours, each mould to draw 2 to stop the capacity, material weight test, another need to test the inner and outer diameter of the mouth, because the mouth of the mould in the use of easy to be covered with oil, resulting in the cover is not strict leakage of wine phenomenon.

Process may be due to the cause of the mould, replace the new into the mould, therefore, change the mould after the molding workshop must immediately notify the quality control workshop, quality control workshop must be a good piece of the new mould out of the bottle inspection and process inspection, to eliminate due to the change of the mould, the quality control do not know and omission of the inspection of the quality of the problem.

Full inspection:

the product from the retreat line out, the quality inspection personnel shall stop the appearance of all products full inspection, it is:

(1) bottle bubbles: bubbles are easy to present in the consumption of glass bottles, most of the inspection quality control personnel can not grasp the correct size.

(2) crooked neck: mainly the operator in the operation, the mouth of the mould and into the mould misalignment or the mouth of the mould side is not complete on the into the mould caused by the request for the operation of the operator to correct the operation can be dealt with.

(3) oblique bottom: the bottom of the material is uneven, half thick, or even more than half, affecting the quality of production, down to the bottom of the product level.

(4) the thickness of the seam line: seam line beyond the appearance of 0.5mm, or even show scratching feeling, is not allowed, especially on the bottle sealing surface is not allowed.
(5) material colour: material colour in general will not make major changes in addition to the composition of the raw materials used in the event of a change in the general will not change, if the phenomenon of green or blue, can be appropriate to adjust the formula to stop the colour.

(6) The inner and outer diameter of the mouth and the mouth of the notch presents: the bottle mouth is clearly present notch, the cap of the inner plug into the plug can not be tight.

(7) seat material (bottle skew): the main reason is that the material is too red (temperature is too), not complete cooling, into the mould forming particles under the seat caused by the moulding out of the product may not be placed on the bottom of the central cause.

(8) shoulder thin: strictly prevent the dead centre does not run material, resulting in thin bladder, resulting in inspection is difficult to grasp, on the way to transport or filling wine, sales in the breakage of larger, resulting in losses.

(9) The bottle body is not bright, and there is a lot of pimple material on the bottle body.-good and bad glass bottles

Incoming sampling:

The quality management personnel will stop sampling according to the AQL counting sampling programme for the rejected batches which have been packaged for warehousing.
Sampling should be all-round sampling as far as possible, and the inspection should be strictly according to the specification or customer’s request.
Qualified batches of immediate storage, stacked uniformly, clearly marked; unqualified batches must be immediately marked, isolated, request rework disposal, until the sampling pass.-good and bad glass bottles-
