Casting resin, commonly known as PU resin, is actually Japanese HEI-CAST resin, which is short for non-foaming polyurethane resin. There are agent A and agent B, and they need the same weight ratio to be mixed.

Colors are white, beige, ivory and so on. (It varies according to the arrangement number of casting resin, such as 80 12 beige, 80 14 white, 80 17 ivory white, transparent color, or other specially modulated colors), light weight, excellent plasticity and best details.

But the price is more expensive than other materials, equivalent to more than 300 yuan per set (one kilogram of A, one kilogram of B, with a total weight of two kilograms). It is easy to process the casting resin by hand, and the casting resin made by hand is mainly the original version.

Japanese handmade materials are generally labeled as cold resin casting kits, and cold refers to the forming process-cold forming, which means that the materials do not need to be heated and melted before entering the mold. Other plastics (such as pvc/abs/) must be heated and melted before injection molding. Resin is resin, and kit means kit. So the translation is cold-formed casting resin kit.

Polystyrene polaroid powder resin

Resin mixed with stone powder, a cold resin. The price is cheap, less than 1/3 of the casting resin price. The English name is poly stone, which is the main material for the early completion of humanoid products. Basically, it is not suitable for manual enthusiasts, and it is the most unsuitable material for GK model. It has the advantages of impact resistance, heat resistance, high hardness, heavy weight, difficult cutting and poor plasticity.

You can change the color by adding toner, which is heavy and brittle (for excellent reasons) and very easy to break.

polyvinyl chloride

Short for polyvinyl chloride. That is PVC material. Europe and America often call it soft rubber material. The uncoated components made of soft rubber (referred to as soft rubber components) are different from the first one in that the components are made of soft rubber, which is cheap and the same shape can be bought with less money. In terms of modification, it has greater freedom than resin.

Extended data

Production process:

Start production

Hand-made will start from the voxel and be made in strict accordance with the set proportion and the structure of the human body. At this stage, proportions and movements need to be completed, and a beautiful handwork, comparative examples and movements are very demanding.

Wait until there is no problem with the elements, then continue to make costume props.

Repeat completion

During the production process, the prototype designer will communicate and meet with the copyright company many times to exchange the production progress and put forward suggestions for revision. This link will be more stringent. Generally, a hand-made project will go through a production cycle of 3 to 4 months.

But in fact, a handmade product can be completed in more than a month, but under the high standards of Japan, this modification process is long.

Many times, in the middle of production, the copyright owner or painter suddenly puts forward an opinion that it is necessary to modify it. At this time, it is very likely to completely overthrow and remake it.

Polishing stage

After the overall details are added, it is necessary to start polishing. Polishing is a key part of a beautiful girl's hand. If polishing is not in place, the surface will be pitted, and excessive polishing will lose many details.

This process is very boring and tests patience. It takes three or four times, from beginning to end, from coarse to fine, to polish a rough hand into a smooth and perfect effect, which usually takes one to two weeks.

Finally, it needs to be copied into gk white mold after polishing. After copying, you need to polish it again to make the parting line smooth, and then you can start painting.

pigment

The painting process of state completion is also very strict, and the most difficult thing is facial painting. The quality of the work depends largely on the face, which is the most testing place in the whole process.

Followed by the overall tone and color matching, a series of color matching will be given in the setting data. However, this color matching can only be said for reference only, and painting still needs to test the painter's color sense and expressive ability.

A beautiful handmade work needs many times of painting to finally achieve a satisfactory effect, and the painting process also takes one to two weeks.
