Common Problems in The Operation Of Silicone Mold Transfer Labels

It looks very simple in the working operation of the silicone mold transfer label,But you will encounter some common problems when you start your hands.Let's take a look at the common problems you will encounter.

Frequently Asked Questions: After receiving the mold,First check whether the mold is damaged or defective.And then how to do it,Find the right time and temperature to adjust during the operation,Here are some frequently asked questions for your reference:

It is not easy to remove the mold. Whether the mold has been treated with Teflon or has not been treated well, it can be treated again.

The hot-melt adhesive film and silica gel are delaminated, and the machine is not dedicated to operate the machine, resulting in poor bonding of the adhesive film and silica gel.The silica gel and the adhesive film do not match, the hydrolysis of the adhesive film fails, the addition ratio of silica gel and curing agent is wrong,There are problems with other additives, the operating temperature is too low, the operating time is too short, etc.As the case may be.

The finished product has air bubbles, and the machine produced does not have a vacuum bonding function.The pressure of the machine is not enough to completely squeeze out the air bubbles in the silica gel, and the oil content of the silica gel is too heavy.The mold is defective, there is no exhaust discharge groove, the surface of raw materials such as silica gel or film has moisture, and there is water in the mold.

The film is cut continuously, and there are rough edges after cutting.The first is whether the pressure of the machine is sufficient, the second is whether the film material is too thick, and whether the cutting edge of the mold is damaged, whether the cutting edge of the mold is passivated due to long use time, and whether the mold is deformed.

The secondary pouring film is not easy to pour, and the choice of the release paper is not correct, resulting in the high viscosity positioning paper not being very sticky.The second is whether the stickiness of the low-viscosity positioning paper in the first pass is too strong, causing the two kinds of paper to generate tension on each other, resulting in easy flipping.The second is wrong technique or operation, which will lead to poor pouring of the second film, depending on the specific situation.

The finished silicone mold transfer label is not firmly ironed on the clothes.There are several situations to look at this issue,First, what is the material of the fabric, because each film or glue has its own characteristics and areas of expertise,For some of the film or glue we commonly use, 85% of them are effective for cotton non-special fabrics.And all of them can pass the commonly used domestic 5A test washing standard.Such as special nylon, water repellent, PU leather fabrics,It is necessary to replace the film or glue corresponding to the targeted bonding of these fabrics for production.Second, the feet are raised after bonding, mainly in two aspects,The quality in the LOGO production process is not well grasped, there is no glue on the warped place,Secondly, the pressing time or pressure is too high during pressing, which leads to the loss of glue and the inability to produce a bonding reaction with the annual material.Third, the temperature or time pressure is not enough, the glue has not penetrated into the fabric, and has not been fused with the fabric.Specifically, it is necessary to judge the specific problem according to the actual situation.

The above are some common problems in the production process of silicone mold transfer labels, and we will share some more detailed and professional problem analysis later.
