Make a custom plastic part. Manufacturing of plastic parts to order

Manufacturing plastic parts to order allows the customer to obtain products of a certain shape in any quantity at an affordable cost. For each order, molds are developed using special technology, which reduces the cost of products and makes them competitive in the market.

Production stages

Here are the stages of manufacturing plastic products:

The production facilities of the Plastics Factory company allow us to cast products of any shape and batch. For production, molds of our own design or those provided by the customer can be used. The raw materials used are our own or supplied.

During the production process, the extruder hopper is filled with granules of polyethylene, propylene or other thermoplastic, which are melted to the technical melting point and fed under pressure into the mold. High pressure makes it possible to produce products of increased strength and complex shapes. After removal from the mold, the plastic blank passes additional processing to eliminate minor defects and quality control. In high pressure casting, the product is ready to be shipped to the customer after removal from the mold.

The advantage of the company "Plastic Plant"

The advantages of the company “Plastic Plant”, which has been operating on the market since 1997, are obvious, because it:

The company works with various thermoplastics, in particular granulated polystyrene, polypropylene, polycarbonate and other thermoplastics are used.

From the moment the contract is concluded to the shipment of a batch of plastic products, a minimum of time passes, the cost of casting does not exceed the market average, and there are no questions about the quality of the products.

A novice “foundryman” should not do this, since each type of plastic has only its own properties, so it would have to be melted at different temperatures. In addition, in production, parts are usually cast in special installations where high pressure is maintained.

Even if you manage to select pieces of plastic of the same type and crush them, bubbles will form when melted. So it’s best to go to a hardware store and buy liquid plastic, from which the parts are no less durable than factory ones. Epoxy resin can also replace plastic. You will also need:
- silicone;
- large capacity;
- .

If you do decide to make something from scrap plastic, do not do it indoors. Plastic fumes are toxic.

Making a form

Make a model of the part you will cast. Coat it with lithol or other lubricant. After that, make the shape. Silicone molds are becoming increasingly popular. This is understandable; working with this material is easy and convenient, but several circumstances must be taken into account. Firstly, there are two types of silicone, pouring and coating. Secondly, each type has its own elongation coefficient and its own viscosity. As for the first parameter, silicone with a coefficient of 200% is suitable for plastic molding.

Pay attention to the viscosity coefficient. The smaller it is, the more accurate the shape will be. This is especially important if you are going to be working with potting silicone. Also take into account the polymerization time. If you have pouring silicone, place the master model in a flask (it can be made of steel or, for example, bronze) and fill it with silicone. Apply the coating material carefully with a brush, taking into account all the unevenness. Let the silicone harden, then remove the master model.

A flask is a metal container. It should be slightly larger than the master model.

A business idea for organizing small-scale production of products from various injection molding materials at home. Thanks to innovative technologies, today in the production of plastic products it is possible to do without expensive automatic thermoplastic machines. Moreover, you can set up small-scale mini-production right on your desktop. This business idea can be considered in two directions:

1. As the main business of manufacturing finished products and molds by casting from: liquid:
   • plastic;
   • silicone;
   • polyurethane;
   • transparent resins and other materials.
2. Mold making as an effective addition to other types of business in the area:
   • construction;
   • Food Industry;
   • soap making.

In the first and second cases, casting at home does not require large investments financial resources. You can start an injection molding business simply now.

Manufacturing using liquid plastics

The manufacturing process is carried out using liquid plastics and silicone molds. Now it is possible to produce plastic products in small batches at home:

• souvenirs;
• toys;
• costume jewelry;
• spare parts for auto tuning;
• spare parts for various mechanical devices;
• shoes;
• dishes

There are components for the manufacture of parts from thin-walled plastic, which can significantly expand the range of products and produce parts of any complexity. For example, mixing two components of the Axson FASTCAST F32 brand from a French manufacturer makes it possible to obtain a super-liquid plastic that flows into the smallest folds of the relief of the model’s shape. In addition, it is harmless to children and has no odor.

Pre-production

To organize production, you will first need a sample model. Using it, you first need to make a mold from special silicone or polyurethane components. With experience and the quality of materials, you can learn to remove molds from models at such a high level that fingerprints will even be visible on the products (if necessary). That is, the copy will be at the level of identity, which cannot be distinguished with the naked eye. Plastic products can be given complex compounds with any relief. If there is no ready-made model for a sample, but you need to make unique products, you can order it from the owners of a 3D printer. By the way, casting significantly exceeds the productivity of 3D printing from plastic.

When your product is ready, it can be decorated using related products that come with liquid plastics:

• paints for artistic effects;
• primers;
• glue.

Naturally, in some cases you cannot do without creativity, and you will have to manually paint the products, which may affect productivity. But creating every business is undoubtedly a creative process. After all, financial management is an art.

We make a product from liquid plastic

The technology for creating an ideal small relief when making it in a silicone mold with your own hands. First you need to prepare all the components and materials. We will need:

1. Silicone Platinum.
2. Liquid plastic Axson FASTCAST F18 (white color, has the consistency of water, odorless!).
3. Scarlet dye for silicone.
4. Polyurethane varnish.
5. Scales.
6. Syringe.
7. File-buff.

We securely fix the sample model to the bottom of the formwork to form the mold, using neutral wax plasticine (to avoid leakage of silicone). We paint the silicone, from which we get the finished form in scarlet color so that the quality of mixing the components of liquid, white to the color of plastic is clearly visible on the form. Helpful advice: in order for the shape to be perfect, you should first coat the sample model with silicone using a wide brush. Thus, carefully fill all the depressions of the relief with compound. Only after this, fill the form completely. We fill the entire formwork with silicone. Leave it for 7-8 hours to fix the mold structure. The hardest part is over.

Congratulations!!! Now you have a ready-made mold for repeated production of copies of the sample model. Before starting casting, make sure the mold is completely dry to avoid bubbles. Then we very carefully mix the plastic components 1:1 by weight (for this it is better to use a pharmacy or laboratory electronic scale). Setting time is 7 minutes, but it will take another 20 minutes to fully set. This plastic is neutral to silicone and does not stick to it. But after repeated use of the compounds over time, you may need a release lubricant with the protective properties of EaseRelease. After the required time has elapsed, we take out the finished product, which is copied exactly according to the sample.

Polyurethane forms for construction

Along with plastic products, injection molds can be produced. The use of injection molds in construction is now very popular. It is possible to produce compounds for the production of building materials. They are durable and do not require treatment with special release lubricants during manufacturing. After all, concrete is absolutely neutral to polyurethane. For example, liquid polyurethane compounds make it possible to produce molds for filling:

• concrete decorative products (tiles, fences, etc.);
• plaster elements of interior decoration (balusters, stucco, etc.);
• liquid plastic when creating a wide variety of products (souvenirs, toys, figurines, etc.).

Silicone molds for confectionery and soap making

The application of mold casting technology in the food industry is quite obvious. New innovative solutions in the field of chemistry today offer liquid: plastics, silicones, silicone masses that comply with all health standards and have the appropriate certificates. Such safe components can be used to make molds for the food industry. For example, for production:

• chocolate;
• caramel;
• isomalt;
• ice;
• mastics.

Compounds are also in great demand among soap makers. They always need new, original molds to create sellable souvenirs made from soap. It is not at all difficult to find a customer who wants to make their products with a unique shape.

Opportunities for a small business idea

This business idea makes it easy to create popular products with your own hands. Finished works can be sold through an online store. It is also possible to provide services or sell finished compounds to other manufacturers in other industries. The most important thing is that with all these wide possibilities of home business, the cost of components is more than affordable. The range of components is wide and allows you to choose necessary materials to create shapes or fill them. All that is required is a sample model from which the mold will be removed. This business idea is very attractive for a home business. It does not require a lot of costs, allows you to produce useful goods and captivates you with the creative production process.
