Do you know
if it will flow. We recommend flow testing before having your molds
built. Post Processing
Our post processing will take your product from a rough finished product to a clean, ready for market, high quality presentation. Many alternative production facilities are limited as to how far they can take a product into completion and ready for the market. At Bee Jay Molding we take pride in the fact that we are able to help our customers from conception to completion. Some of the processes we offer are as follows.
Sonic Welding
Sonic welding post processing uses an acoustic tool to transfer vibration energy through the plastic parts and into the weld area. The friction of the vibrating molecules generates heat, which melts and welds the plastic. When the plastic reaches a molten state, vibration stops. Apply pressure while the molten plastic solidifies and you have a welded joint.
Screen Printing
Often called silk screen printing from the material formerly used for the screen. This is a stencil process with the printing and non-printing areas on one surface. The printing (image) area is open and produced by various forms of stencil. the substrate is placed under the screen and ink is passed across the top of the screen and forced through the open (printing) areas on to the substrate below.
Hot Stamping
Hot-leaf stamping post processing is a decorating process in which a metal foil or pigment is placed on carrier films. A heated die is used to press against the foil and plastics, and the foil or pigment is released from the carrier film. It is the heat and the pressure of the process that bonds the decoration to the substrate.
Hot-foil stamping is a popular process for decorating plastics. The foil must be compatible with the plastic substrate to be decorated.
Pad Printing
Used for printing across relatively small areas on plastic items and when the area to be printed is difficult to reach at or is contoured.
This method uses a silicone ball/pad to lift the color and design off of a plate and then transfer it onto the surface of the item to be imprinted.
An inked image is transferred from a photo-etched plate to a thick, soft silicone pad. The pad is then pressed against the plastic part. The pad can wrap itself as much as 180° around a small object, and ink coverage is excellent. One color is done at a time, but registration between colors is good enough to allow four-color process printing.
