3) Casting Die Size 1 The geometry and dimensions of the casting mold shall conform to the provisions of the casting pattern.
2 The dimensional tolerances of casting moulds shall be in accordance with the provisions of GB/T 6414-1999. When there are special regulations and requirements, they must be indicated on the drawings.
3 When casting molds have shape and position tolerance requirements, reference may be made to Table 5; the marking method is in accordance with the provisions of GB/T.
4 The dimensional tolerances of casting molds do not include the casting slope, and its non-processed surface: the envelope surface is based on the small end, and the enveloped surface is based on the large end; the surface to be machined: the envelope surface is based on the large end, and the envelope surface is The small end is the benchmark. When there are special regulations and requirements, it must be noted on the drawings.

3 casting molds allow scratches, dents, lack of meat and mesh burrs and other defects. However, the extent and quantity of its flaws should be consistent with the standards agreed by both parties.
4 Gates, flashes, overflow ports, partitions, and ejector pins should be cleaned. But allow traces.
5 If there is no special regulation on the drawing, the setting of the die casting process, such as the position of the ejector pin, the position of the parting line, the position of the gate, and the overflow port, shall be stipulated by the manufacturer. Otherwise, the pattern shall be marked or both Agreed.
6 Casting molds require specially machined surfaces, such as polishing, shot peening, chrome plating, coating, anodizing, chemical oxidation, etc. must be indicated on the drawing or agreed upon by both the supplier and the buyer.
LED grow lights are relatively new to the cannabis growing scene,but they have become wildly popular over the last few years with their ability to produce great yields while staying cool and using a reasonable amount of electricity.

Cautions:
1.Do not use the lights in dripping water or anywhere where they will get wet, water and electricity can be a dangerous mixture
2. The working environment for the light is -20~40 degree celsius,45%RH~90%RH.
3. To protect the light, Plz cut off the power when there is a lightning strike.
4. Don`t touch or move when the light working.
Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3.Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4.While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp.
