The Customer:

Amper-Plastik R. Dittrich GmbH & Co. manufactures technically demanding injection molding parts for the electro/electronics-, automotive and medical industry. With technologies like insert molding, wire insert molding or two component injection molding, the company is positioned as a powerful mid-range entrepreneur.

The Task:  

Fabrication of different injection molding parts for computers in a flexible production cell.

The Problem:

A future prove “no-worry” invest by optimized joining of machine and automation

The Solution:

KraussMaffei configured a fully automatic production cell, consisting of an injection molding machine of the type CX 200 and a LRX 100 linear robot. The parts are injected, afterwards demolded by the robot, partially inclusive sprue. Due to the reason, that many components become post-processed (e.g. metallized), the main focus lies on high precision and cleanliness. The IT elements afterwards are precisely positioned and packed. An integrated testing unit compares the parts with defined specification parameters; rejection parts are recycled immediately by a mill.

The Outcome: 

One very successful product group are different keyboard keys, for the European or the US market. Depending on language and special characters, a 32 or 23 cavity vacuum gripper is installed on the wrist axis of the robot by quick change unit. A pipe manifold guarantees the fully automatic separation and packaging of keys, according to the different cavities. This manifold can be installed above the standard conveyor belt included in the production cell. The robot unloads the keys exactly above a funnel plate; via pipes, the parts get into bags, which are installed underneath. A safe process is ensured by coding of the pipe manifolds.
