Tips About Pipe Fittings Injection Robot Selection

Axis Definition

injection robot

Tips: To select a suitable injection robot for your pipe fittings injection project, beside the size of the robot, it's also very important to take care the payload of the injection robot, especially the robot for an in mold insertion application. For PVC/PPR pipe fittings with metal inserts, the robot will pick both the parts and the insert and must insure the inserts could be inserted into the mold precisely, which will make the weight of the EOAT much higher than a standard one.

Robot Sizing

injection robot
  • L: The max length of the robot
  • Z: The max distance where the parts to be dropped
  • Y: The max distance movabel of the robot arm from the standby position to the mold center
  • W: The width of the robot
  • H: The height of the robot
  • Hs: The height of the robot stand
  • YM1: The height from the standby position to the top of the machine
  • YM2: The distance from the Machine top to the mold center
  • X1: The max distance of the main arm from the mold platen
  • X2: The working stroke of the main arm
  • X3: The Min distance between the main arm and the sub arm of the robot
  • X4: The Max working stroke of the sub arm
  • X5: The Min distance from the sub arm to the mold platen

Robot Installation

injection robot
  • A -- Non-operator side installation of the robot
  • B -- Operator side installation of the robot
  • L -- The height of the crane
  • E -- The distance from the floor to the mold center
  • G -- The distance from the floor to the safe door rail
  • N -- The height from the top of the injection molding machine to the mold center
  • H/J -- Distance between the tia-bars
  • The Height of the Safe Door -- D-N

Tips: The primary principle of selecting a robot for your injection automatio project is that to make sure:

  • Picked: The robot arm can reach the mold center to pick the parts
  • Pickable: The robot has sufficient payload to carry the parts + EOAT
  • Pick out: There's enough in mold space to pick the parts out
  • Placeable: The parts can be carried over the safe door of the injection molding machine
  • Speed: The robot must be fast enough to match the injectio cycle
  • Arms: Choose single or double arms according to the mold type
  • Arm Type: Choose standard or telescopic arm according to the height of the crane
  • EOAT: For complex structure plastic parts, a set of custom made EOAT would be necessary
  • Special Requirement: For the robots to be integrated into an automation system, some special requirements would be requested, a custom made robot would be in this case

Q & A About A Pipe Fittings Injection Automation System
  1. Will there be a system available for different sized pipe fittings?

    For any automation system include an automation system for pipe fittings, it would be custome made for specific products to ensure the productivity of the system and reduce the possible alarms of the system. So an economic automation system would be a system of bulk production of single size pipe fitting of the same material.

  2. For two same size PPR/PVC pipe fittings, is it possible to use the same runner cutting system to remove the sprue ?

    As for this question, it'll depends on the quality requiremnt after cutting. Due to the differenet character between the PVC & PPR, we can use a Pneumatic sheet to remove the runner of a PVC pipe fittings but for PPR pipe fittings it's better to have a punching knife to have the sprue removed to ensure the runner cutting quality.

  3. For small size pipe fittings with insertion, a mould of how many cavities would be regarded an economic one for the automation system?

    For an automation system for small size connectors with in mold insertion, 8 cavities would be an ideal mold design in regard the investment and the complexity of the pipe fittings injection system. With an 8 cavities mold, you'll need to invest an injection molding machine of around 200T and an injection robot with payloade around 15kg, it would be an economic option with an easy maintenance automation system.

  4. For a pipe fittings injection automation solution, what information to be provided to ensure a success of the project?

    For a pipe fittings injection automation system, the information what we need would be:

    1. The 3D drawing of the mold
    2. The 3D drawing of the insert
    3. The details of the injection molding machine
    4. The detailed quality standard of the final products
    5. The material of the pipe fittings
    6. The total cycle time
