Plastic molds are the abbreviation of assembled plastic molds used for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding. They are mainly composed of concave combination substrates, concave combination substrates and concave combinations, concave with variable cavities formed by pallets, convex combination substrates, convex combination substrates, convex combination pallets, cavity cutting units, and side-cut combination plates.
Through the coordinated changes of the convex mold, concave mold, and molding system, a series of molded products of different shapes and sizes can be processed. So, let's learn about the structure and composition of plastic molds together! In order to improve the performance of plastics, various materials such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. are added to the polymer to make it a plastic with good performance.

1. Synthetic resin is the main component of plastics, and its content in plastics is generally 40% to several hundred percent. With high content, the properties of resin often determine the properties of plastics, so resin is often considered a synonym for plastics. In fact, resin and plastic are two different concepts. Resin is an unprocessed raw polymer. It is not only the manufacturing of plastics, but also the raw material of coatings, adhesives, and synthetic fibers. Except for a small part of plastics containing resin, most plastics need to add other substances in addition to the main component of resin.
2. Fillers can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce costs, making phenolic plastics one of the cheapest plastics, while significantly improving mechanical strength. There are two types of fillers: organic fillers and inorganic fillers. The former includes wood powder, rags, paper, various textile fibers, etc., and the latter includes glass fiber, diatomaceous earth, asbestos, carbon black, etc.


3. Plasticizers increase the plasticity and softness of plastics, reduce brittleness, and facilitate the processing and forming of plastics. Plasticizers are generally mixed with resins. They are high-boiling organic compounds that are odorless, odorless, heat-resistant and stable. Phthalate esters are commonly used. For example, when making polyvinyl chloride plastics, adding more plasticizers can obtain soft polyvinyl chloride plastics, but when no plasticizer is added or the amount added is reduced.
4. Stabilizers are added to plastics to prevent synthetic resins from being decomposed and destroyed by light and heat during processing and use, and to extend their life. Commonly used ones include stearates, epoxy resins, etc.
5. Colorants can give plastics a variety of bright and beautiful colors. As colorants, organic dyes, and inorganic pigments are often used.


6. The role of lubricants is to prevent plastics from sticking to the mold during molding, and at the same time make the plastic surface smooth and beautiful. Commonly used lubricants include stearic acid and its calcium and magnesium salts. In addition to the above-mentioned additives, flame retardants, foaming agents, antistatic agents, etc. can also be added to plastics.




Q1: Are you a manufacturer or a trading company?
A1: We are a 100% manufacturer with multiple skilled workers and experienced sales staff.
Q2: Can you sign a confidentiality agreement before we transmit the product size data to you?
A2: We guarantee to keep your design and content secure and confidential. If needed, we can sign an NDA document for you. You can send your company's NDA to us directly, and we will sign it back to you.
Q3: How can I customize a product?
A3: Provide relevant documents (2D and 3D drawings).
A3:Tell us your requirements for the parts (hardness/material/quantity/color, etc.).
3. After analyzing with our engineers, a quotation will be made within 24 hours.
Q4: What is the minimum order quantity for liquid silicone products/plastic products/encapsulated waterproof parts, etc?
A4: For traditional ready-made materials, 8000 pieces can be ordered. If it is a customized product, the minimum order quantity is determined based on the minimum requirements of different materials.
Q5: How does your factory do in terms of quality control?
A5: Quality is the top priority. We always attach great importance to quality control from the beginning to the end of production. Each product will be fully assembled and carefully tested before packing for shipment.
Q6: How about the delivery time?
A6: The estimated delivery time is different for different products, generally speaking, it is about 4 weeks to 8 weeks.
