When a plastic bottle was produced by a hollow blow molding machine, it was found that the cap did not function as a burglarproof, but was caused by a large diameter of the burglar ring at the mouth of the bottle. The reason why the diameter of the anti-theft ring is too large is directly caused by the large diameter of the anti-theft groove on the mold. Find out the crux of the problem, the usual method is to re-mold the mold. At the same time, it takes a certain amount of time to re-make the mold, which will inevitably affect the entire production cycle. In response to this situation, we decided to use bonding technology to repair the mold; the specific steps are as follows:
(l) Firstly, 0.1 thick copper foil is cut into two strips with scissors. The width of the strip is slightly smaller than the width of the anti-theft groove on the mold to facilitate bonding; the length of the strip is equal to the circumference of the anti-theft slot. One part; (2) use a cotton swab to rub a little gasoline, wipe the anti-theft groove on the mold and the front and back of the copper foil; (3) mix the two components of the modified epoxy resin adhesive in proportion, and evenly apply it on the copper foil. On the bonding surface, it should be noted that the adhesive layer is not too thick, otherwise the adhesive will be squeezed out from the gap between the copper foil and the anti-theft groove during the pressure curing process, which will eventually affect the geometry of the anti-theft ring on the bottle mouth. In case of seriousness, the mold repair work may even fail; (4) a standard plastic bottle is placed in the mold, and then the mold is clamped to cure the adhesive under pressure for 4 hours; (5) after the adhesive is cured, it should be tried first. A number of plastic bottles, after the products to be tested are qualified, can be officially mass-produced plastic bottles.
Practice has proved that the proper use of the bonding process to repair the mold is simple, easy, economical, and highly reliable. Moreover, since the mold does not need to be disassembled during repair, the mold release, mold loading and mold time are saved. , greatly reducing the loss of downtime, so that the repaired mold can be quickly put into normal use, creating more and better economic benefits for the enterprise.

The Installation of Mounting Unit
1. Make the concrete base according to solution drawing, locate embedded bolts and set out strings by Laser Level to ensure the centers of embedded bolts in the same elevation as accurate as possible on vertical, horizontal direction and at end face.
2. Locate the Anchor Plate on the concrete base and adjust the position according to solution drawing(remove M14 washer,M14 spring washer,and M14 nut if they are connected to embedded bolts now),and then fasten M14 washer, M14 spring washer, and M14 nut with the tightening torque of 60N.m.
3.Take out the Hexagon Bolt Kit with Post B Corrugated Gasket M12x95 and remove its nut, spring washer, one washer, and corrugated gasket. Insert the Post A, B, C in to Anchor Plate according to the Hexagon Bolt Kit with Corrugated Gasket M12x95 drawing and then fix them by two sets of Hexagon Bolt Kit with Corrugated Gasket M12*95. Post C Post A
4.Remove the bolt kits M12*90 from all the Posts and Pre-Assembled Supports and unfold the embedded Supports, fasten them on the Posts by bolt kits M12*90 according to the drawing.
Installation of Rails
1.Please check the length of Beam before place it onto the Pre-Assembled Supports, otherwise extend it with Splice forBeam first. There are 4 self-tapping screws in each side and total 8 self- tapping screws in both sides. We strongly recommend NOT extend the Beams on Preassembled Supports.
2.Before locate the Beams, mark the position of the Beam son the surface of Pre-Assembled Supports with maker pens according to solution drawing for easier installation. Place the Beams on the 55*80 Tube of Pre-Assembled Supports and fix it with C Clamp Kits. Install all the Beams in the same step. The tightening torque will be 20N.m. C Clamp Kit Side Beam(Please arrange 3-4 persons to install when the array is long.)
Installation of Solar Panels
1.Place the panels above the Beam 85, fixing it with Wide End Clamp Kit in the side and Inter Clamp Kit in the middle. Install all the panels in the same steps until complete installation of al panels. Fasten all the bolts with tightening torque of 10N.m.
2.Complete installation, and please inspect and make sure all the bolts are fastened.
