Automatic Metal Spraying Machine

INTRODUCTION
Over the years of experience, we have achieved expertise in the developing and providing Automatic Metal Spraying Machine in varied specifications as per the needs of the clients. For more details about our Automatic Metal Spraying Machine, please contact with us immediately.

The Metal Spraying is a very critical operation in the manufacture processes of metallized film capacitor. Since the metal particles are produced by wire melted and high velocity to coat in the end faces, it makes contact with the capacitor winding primarily by partial penetration of the pockets in the end faces formed by staggering the films. Factors which affect the degree of penetration are mainly the velocity of the metal spray particles and their size. So the following important factors are influential capacitors quality: The temperature of metal spray particles, the size of metal spray particles, the velocity of metal spray particles, the average of metal spray particles

Incorrectly selected spray equipment can cause severe damage to end faces of the windings and produce unacceptably high power factor capacitors. The AUTOMATIC METAL SPRAYING MACHINE is designed through our comprehensive research and accumulated ten-year of experience; as the requirements of regarding above specially performance of metal spraying in metallized film capacitor.

It is including following parts, and its specification and function as following.
POWER SUPPLY
A. CHARACTERISTIC
◆This structure is input power of AC three phases, through one set of voltage regulator and one set of three phase full wave rectifier, so output one set stable DC power to supply the requirement of Spray Gun.
◆Compressed Air System, power output and power source of Spray Gun are controlled by an uniformcircuit with reasonableness and effectiveness.
◆In order to ensure quality for spraying, the Compressed Air is filtered by one set of oil and water filter, also through a pressure switch to detect.

B. STRUCTURE: The components chart as following:

SPRAY GUN
A. CHARACTERISTIC
This is particularly designed to satisfy the requirement of above mentions properties of metal spraying. It is together with following superior functions:
  • The spraying material require metal wire of Al., Tin, Zinc, Lead...etc. or the alley of them.
  • The transmission is controlled by DC motor, the speed is adjustable and have durability for long time spraying.
  • The nozzle between Ø1.2～2mm are changeable (Standard is Ø1.6mm), also it is easy to change and cheapness cost.
  • Through constant housing to fix the wire intersection angle, also it is simple assembly and without adjustment.
  • With specially air flow separator, the device can reduce noise and cooling nozzle operating temperatures and nozzle wear with a consequent saving in downtime to lengthen life. Importantly the air flow separator assemble the Al. cover at a predetermined angle to direct the atomizing air flow between and around each wire. This result in better atomization and a more dense coating than previously attainable further improves coating quality deposit efficiency, density, and reduces coating oxide contact. The new- type of spray results has more improvements than old-type, which is a important of critical cause for capacitor's quality.
B. SPECIFICATION
It is particularly designed in order to get rationalization and automation in spraying process. The functions and characteristics as following:
  • Only to set the reference values then operator put protected capacitor's element together with plate in entrance of Automatic Spray Fixture, so it'll automatic load → position → spray → account → move and output. It is able to easy get the consistent coating quality.
  • in order to avoid material consuming after the element plate positions, then begin the spraying action.
  • it' is adjustable for the action of time, speed, times and spraying distance, also it is suitable for the demand of spraying feature of the different capacitors.
  • In order to avoid operator damaged for metal spray particles and noise, so it could be separated with worker by far operation.
TRANSMISSION METHOD By DC motor (DM09-5GN-5), speed adjustable. Voltage: DC 90V, R.P.M.: 1800
MELTING METHOD By electric ARC type
ATOMIZING METHOD By high air pressure
MATERIAL Metal wire such as Al., Tin, Zinc, Lead...etc. or alloy of them.
WIRE OUTER DIAMETER Ø1.6mm Al., Tin, Zinc, Lead...etc. or alloy of them.
DIMENSION W 380 x H220 x D220 mm
WEIGHT 7 KGS
