1. What is the mold used to make the resin table?

A typical fence structure can be done. Because the river table is mostly in the form of a board surface and not very thick, it can generally be made without any special molds. You can find some pvc boards or other flat boards as frame fences, both are ok. If you use glass plates or metal plates, you can use some mold release materials, such as mold release wax, for smoother demolding.

2. What material is used to make resin mold?

A typical resin glue mold is referred to as a glass fiber reinforced plastic mold, or glass fiber mold, which is generally composed of glass fiber and resin hand-laid laminated composite.

The main materials of the resin glue mold are glass fiber, resin glue and mold gel coat. Other materials include some mold release wax, curing agent, polishing wax and so on. Glass fiber has 30g surface mat without alkali, 300g chopped strand mat and 400g gingham cloth. The resin includes vinyl resin or unsaturated resin and epoxy resin, etc. The mold gel coat generally uses vinyl system.

If you want to know the specific mold materials to be used, it is recommended that you contact your local composite material distributor. Generally, they will provide you with a complete list of mold making materials based on your actual situation.

Plastic mold processing is basically divided into static mold

Plastic mold processing is basically divided into static mold and movable mold. The one with sprue sleeve on the side of the injection head processed by the plastic injection mold is a static mold. The static mold generally consists of a sprue sleeve, a backing plate, and a template. A simple mold can also use a thicker template instead of a backing plate. Up. Plastic mold processing sprue sleeves are generally standard parts, and it is not recommended to cancel unless there are special reasons. The use of sprue sleeves for plastic mold processing is conducive to mold installation and easy replacement, without self-polishing. Plastic mold processing Some special mold sprue sleeves can be drilled out or cut by taper line cutting. When part of the mold must be demolded from the static mold, the static mold release mechanism must be added. The structure of the movable mold for plastic mold processing is generally a movable template, a movable mold backing plate, a demolding mechanism, and a mold foot and a fixed plate for the installation.

In addition to the stripping rod, there is also a return rod in the demolding mechanism. In the injection molding part of the plastic shell, a spring must be added to realize functions such as automatic demolding. The basic structure of the mold is also indispensable for plastic shell injection processing, as well as guide posts, cooling water holes, and runners. Of course, the inclined guide mold also has inclined guide boxes, inclined guide posts, etc. When designing a mold for a product, the plastic shell injection molding process must first set the basic structural dimensions of the mold to prepare materials to speed up the mold manufacturing. Plastic shell injection molding complex products should first draw the product picture, and then determine the size of the mold.

The gate is directly related to the beauty of the plastic part. If the gate design is not good, defects are likely to occur. It is easy to produce snake-like flow when the plastic shell is sprayed without any obstruction. Plastic shell spraying should also be designed for overflow and exhaust for products with high requirements. The ejector pin can be used at the overflow, and there should be no overflow flash on the template, so as not to affect the life of the mold. There are also more and more software for plastic shell spraying design molds, and most of them rarely use pencils to draw mold drawings.
