The surface treatment of the inner mold glue surface must be carried out in accordance with the BOM list or other officially notified technical requirements. The processing texture on the non-glue surface (wire cutting, milling machine, CNC gong machine, spark machine) should also be polished with a whetstone.

All the front and rear inner molds, inserts, row positions, inclined tops, straight tops (push blocks), shovel chickens, etc. of all molds need to be processed with a waist-round pit on the bottom or side, and the material name and hardness are engraved.
10
Important easy-to-wear parts such as the row position, push block, shovel chicken, and mouthpiece must be nitrided and hardened.
11
The rows must be positioned. Positioning methods include slingshots, wave beads, HASCO (DME) standard positioning clips, etc. The specific requirements need to be according to the requirements of each project. The row position needs to have battens and wear-resistant plates. Layers and wear-resistant plates must be made of wear-resistant hard materials, and an oil groove needs to be added.
12
13
Sloping-top seats must be made of wear-resistant hard material. The inclined roof must be processed with an oil groove. The inclined roof base is generally hardened with 2510 or CR12 to HRC40-45 degrees. Because the inclined roof base is subject to impact load, it cannot be too hard or it will break. C-angles must be chamfered at all right-angled positions. . A sloped roof guide plate (bronze) is required. No welding allowed.
14
The flow channel and glue feeding position need to be glossy #400-600.
15
The ejector pin, cylinder, ejector pin, inclined ejector and ejector plate should be engraved with corresponding identification codes to facilitate installation. If the position of the ejector pin on the product is not horizontal, the ejector pin seat needs to be made into a "D" shape or positioned using an anti-rotation pin key.

When processing the groove of the water-carrying apron ("O" ring), a gap of 0.25mm needs to be reserved on one side. Generally, the apron needs to be pre-pressed by 0.5-0.8mm. If you do not pay attention to this, the apron will be easily crushed and damaged. causing water leakage.
18
The mouth of the mouthpiece needs to be nitrided and needs to be anti-resale. The radius of the spout must comply with the drawing requirements. The nozzle is not nitrided and may have been damaged before the mold was moved.
19
Conventional structure molds must be equipped with support heads, and both end surfaces need to be ground flat. The small mold is preloaded by {{0}}.1mm, and the large mold is preloaded by 0.1mm-0.15mm.
20
Please refer to the BOM list or confirmed mold drawing for the specifications of the faucet. The countersunk hole of the faucet must be processed and installed according to the mold drawing. Drilling holes must not be drilled off-center, and sharp corners must be chamfered.
Water transport must be marked in1, out1, in2, out2………….
25
All screws and mold accessories must be standard parts, and the screw heads cannot be sawed off. The effective locking length of the screw must be sufficient, normally 1.5 or 2.

Before moving the mold, the water pressure needs to be tested (above 100pa). After the water is accepted, the water needs to be blown clean with an air gun.
