- Page 2 The option was intended to allow the end-user to repair damaged cable jackets. The purpose of this manual is to explain in more detail how to operate a Model 50 machine with the 'C' frame option.
- Page 3 INTRODUCTION 'V' Mold for Overmolding Cables Miniature Plastic Molding offers a 'V' mold designed to overmold damaged jackets on cables. The mold contains a large pocket to surround the damaged area. Either end of the mold contains a groove large enough to hold the cable, but small enough to prevent material from squirting out.
- Page 4 INTRODUCTION Optional 'C' Frame Base An option available for the Model 50's is a 'C' frame base. The optional base is similar to the standard base, except it is rotated 90º. The frame has also been modified so that the front of the machine is left open.
- Page 5 Equipment Setup Set Barrel Temperatures The Model 50 machine has two pyrometers to control the temperature of the barrel and nozzle. Set the temperatures to the recommendation of the material's manufacturer. With cable overmolding it may be required to increase the temperature to the upper range of the material.
- Page 6 Machine Operation Listed below are recommended steps for cycling the machine. Use these steps as a guideline for operating the machine. Most of the steps shown are also the same steps used in standard molding applications. (1) The first step is to prepare the shot by filling the barrel with material. When filling the barrel, do not use a mold or purge plate in the 'V' clamp.
- Page 7 Machine Operation (3) Manually run the plunger down to push material into the mold. The Inject/Start Cycle position is a maintained position, so the operator does not need to hold the switch to keep the plunger from stopping. To run the machine in manual operation, the timer switch is in the off position.
