Filling is the first step during whole injection cycle, and the present invention uses high-speed filling method, molten to being filled in mold cavity
Melt plastics too；
The effect of pressurize is continu to press, is compacted melt, increases plastic density（Density）, to compensate the contraction row of plastics
For the present invention sets dwell pressure 60-80MPa according to the molten condition and filling effect of four-stage；
Cooling is that automotive upholstery needs cooling and solidifying to be molded after injection moulding in die cavity, therefore the present invention is using in mould inside
Cooling water pipeline is set, and the water circulation in cooling water pipeline flow to cooling water system, cools down the speed of current first quick and back slow；
7）The demoulding：Workpiece after cooling is taken out；
8）Surface quality is checked；
9）Cleaning：Remove intake material；
10）Whole inspection, packaging and storage；
2）PVD priming paint
A, pre-treatment：Wiping treatment is carried out to automotive upholstery material using isopropanol, surface grease is removed, wiping process is used
First soaked 5-10 minutes in aqueous isopropanol, then surface wipes are carried out to automotive upholstery during immersion, wiped
Cleaned 2-3 times with clear water afterwards；
B, preheating：Because long-time is deposited, the moisture in material meeting absorption air, by preheating operation removal automotive trim
Moisture in part material, the programming rate of heating-up temperature is 1.5-2 DEG C/min, and temperature is progressively heated at 50-60 DEG C, heat preservation and dryness
Evaporation moisture；
C, dry ice pre-treatment：After automotive upholstery material after preheating is gradually cooled to normal temperature, further removed by dry ice
The grease that material surface just remains, the more effectively grease of removal material residual, it is ensured that properties of product；
D, spray-applied primer：Using manipulator spray can preferably ensure coating layer thickness, primer coating film thickness monitoring in 15-20um,
Painting environments, 20-25 DEG C of temperature, humidity 50-70%；
D, heating levelling：Above-mentioned automotive upholstery material surface is directly heated, is directly added using Far-infrared Heating mode
Heated work pieces surface, can preferably ensure that workpiece surface temperature is uniform compared to traditional hot air circulation, and ensure to paint wet film levelling
Uniformity；
E, solidification：Condition of cure：Energy 1600-1800mj/cm2, intensity 120-140mw/cm2, can be with using UV curing modes
More thorough cured paint film, condition of cure is controlled in the range of, and energy is too high to cause paint film brittle, too low to be fully cured,
Cause the pumpdown time long during plating, intensity bottom can not deeper permeate paint curing, intensity readily permeable paint high,
Material is caused to damage, conditions above control is bad all to easily cause the reduction of PVD performances；
3）PVD plated films：Between 2-3um, because coating belongs to metal, the ductility from coating is different for zinc coat thickness control,
In the range of can reach equalization point with paint film coating；Plated film room environmental, 20-25 DEG C of temperature, humidity 40-50%, control humidity can
To accelerate PVD equipment to vacuumize, because coating belongs to metal, the temperature difference of environment easily causes coating surface and plays steam, causing property
Can be bad, so temperature must be consistent with surrounding enviroment, it is maintained at 20-25 DEG C；
4）PVD colored paints
A, preheating：Using Far-infrared Heating mode, temperature 60 C/3min can effectively remove workpiece surface coating residual water
Vapour, and reduced if workpiece surface has steam to directly contribute properties of product, adhesion declines；
B, electrostatic precipitation：Using reciprocating high-pressure electrostatic precipitation, without dead angle, product percent of pass is improved；
C, spraying colored paint：Sprayed using manipulator, uniform film thickness, film thickness range is controlled in 5-8um, and thickness is high easily to be covered
PVD, it is reflective effect not have with PVD；
D, heating levelling：Using IR mode of heatings, that is, Far-infrared Heating mode, workpiece surface is set to receive temperature evenly, levelling
The good no color differnece of effect, heating-up temperature is 60 DEG C/3min；
E, solidification：Condition of cure energy 900-1000mj/cm2, intensity 150mw/cm2, the thin solidification energy bottom of film layer, and ensure paint
Film layer nondiscolouring；
5）Laser carving：The automotive upholstery material treated through above-mentioned steps is first navigated on proprietary positioning tool, it is ensured that undercuted
Homogeneity of product；Using laser laser engraving machine laser carving, laser energy, laser carving speed 3200-3500mm/s are controlled；
6）PVD finish paints
A, electrostatic precipitation：Using reciprocating high-pressure electrostatic precipitation, without dead angle, good dedusting effect further improves product percent of pass；
B, spray paint：Sprayed using manipulator, uniform film thickness, film thickness range control is in 10-15um, painting environments, temperature
20-25 DEG C of degree, humidity 50-70%；
C, heating levelling：Using IR mode of heatings, workpiece surface is set to receive temperature evenly, heating-up temperature is 60 DEG C/3min；
D, solidification：Condition of cure：Energy 1500-1700mj/cm2, intensity 120-150mw/cm2. are more thorough using UV curing modes
The cured paint film at bottom, condition of cure is controlled in the range of, and energy is too high to cause paint film brittle, too low to be fully cured, intensity
Bottom can not deeper permeate paint curing, and intensity readily permeable paint high causes material to damage, and conditions above control is bad all to be held
Easily cause the reduction of PVD performances；
Referring to the drawings shown in 4-5, in the present invention, heated using infrared heating means in " preheating " operation, institute
Stating Far infrared heating method automotive upholstery material is placed in into drum type brake infrared heating equipment carries out heating operation；The cylinder
Formula infrared heating equipment include heating cylinder 101 and heat-insulation layer 102, the heat-insulation layer 102 and it is described heating cylinder 101 it
