Supply refrigerator drawer mould-SINOMOULD

Sino mould is a very professional mould maker for refrigerator drawer mould in China.with so many years of mould production,Sino mould owns our special production system and standard.SINO has delivered a lot of refrigerator drawer moulds all over the world,such as Brazil,Spain,Mexico,Israel,France,USA…

In each part of the refrigerator,the inside drawer plays the role of carrying heavy loads,directly affects the weight of the refrigerator.Generally the refrigerator drawer is the quality of plastic,PP,PC material is in the majority, for this kind of products,usually require transparent color,light quality, surface roughness higher,there can be burr,rower phenomenon.

Injection molding is the common way to forming the refrigerator drawer mould.And refrigerator size is big,adopt single cavity is ok.Consideration the high quality surface treatment request,Valve gate type hot runner system commonly will be used as the main forming way.

Welcome to make any enquiry or if you need any help on moulds production,please feel free to contact us.

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.
