Injection mould decoration (IMR) process-Sino mould

As the world economy level of development,the industrial design requirements more and more attention to fashion,environmental protection,lightweight design,IMR technology emerged,has been widely applied in all walks of life,from the earliest consumer products such as notebook shell,mobile phone lenses,household appliances all kinds of decorative panels,car dashboard,car inner decoration,medical instrument panel,cosmetics boxes,children's toys and so on.

What is the IMR?

IMR (In-Mould Decoration by Roller):Chinese model inside decoration,is the decorative pattern and functional pattern through high precision printing machine printing on foil membrane (film),through high precision to foil device will foil into the special toolings for precise positioning,through the injection plastic raw material of the high temperature and high pressure.The foil pattern on the membranes of the transfer to the surface of the plastic products,is a kind of decorative pattern and plastic molding technology can be implemented.

The principle of IMR
Design printed on a layer of foil membrane,through the diaphragm and plastic model cavity of film laminating for injection molding,injection molding of pattern after the ink layer and foil membrane separation,ink layer on the plastic parts for surface decorative figure.

Transparent products injection common problems in the process of formation and countermeasures

Transparent products products relative to other luster, there will be particularly obvious if appear surface appearance problem.In the process of the injection molding bad ratio is relatively high.


Common trouble spots are air bubble,weld line and black spots.
The following simple parsing the reasons and countermeasures.
1,bubbles,porosity may cause:melt temperature is too high, lead to materials decomposition;Low injection pressure,mold temperature,holding time short lead to bad materials for the products;Insufficient material drying, impurities in molten material inside the foreign body.Improvement countermeasures:appropriate reduce melting temperature,improve the injection pressure,mold temperature and the holding time.Material is fully dry.

2,welding scar, possible reasons:low melting temperature,mold temperature, injection pressure,the holding time is insufficient,lead to poor liquidity in the molten material in the cavity;Mold venting is not good;Design of gate location is not reasonable to improve countermeasures:to provide the molten material,mold temperature,injection pressure increased time,is the rapid filling material.Increase exhaust slot,redesigned into glue.

3,black spots may cause: materials of impurities;Melt temperature Settings,which leads to the materials decomposition;Gun barrel and stagnation expected nozzle segment.
To improve countermeasures: material thoroughly remove replacement, melting temperature appropriate adjustments,cleaning gun barrel and the nozzle.

The standard for the injection machine and machine robots connection-Dakumar injection machine

Injection molding machine and the interface of the manipulator is a handshake protocol,coordinate the order of the injection molding machine and manipulator.Interface defines the machinery installation and electrical agreement,the current domestic use more generally accepted standard is the European standard 12, European standard 67,domestic there are a lot of injection molding machine manufacturers,but with the manipulator interface of various electric agreement.At present most of the injection molding machine equipped with 32 core interface.

Many domestic injection molding machine manipulator interface signals usually only a few manufacturers,as shown in the following:

Injection molding machine manipulator to signal:stop,exit,mould and finished, automatic state.
Robots for injection molding machine:signal interlock,allowed out,take out.

Interface is injection molding machine and manipulator of language communication, injection molding machine manufacturers,manipulator manufacturers, if a user can follow to follow this kind of language,so can bring convenient to each other.

Dakumar injection molding machine company is the professional moulds,Injection machine and robots manufacture,we can offer you turnkey project solution on-stop solution.
