Plastic injection molding
Plastic injection molding is a process of manufacturing products by injecting high-pressure thermoplastic into molds, suitable for large-scale mass production.
A type of injection molding manufacturing process in which prefabricated metal or other material parts are first inserted into a mold, and then molten plastic is injected to solidify and tightly bond with the insert.
A manufacturing process in which a plastic material is moulded onto another plastic material to create a component. Improve the functionality and aesthetics of the product, increase the soft grip and multi-color design and other functions, thereby improving the practicality of the product.
All thermoplastic materials can be injection molded. Certain types of silicone and other thermosetting resins are also compatible with injection molding processes. The most commonly used materials in injection molding are:
Also known as polyamide, it has good mechanical strength and wear resistance.Suitable for gears, bearings, sports equipment, and industrial components.
Divided into low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE).Features include good chemical stability and electrical insulation, suitable for manufacturing plastic bags, bottles, toys, etc.
Has good mechanical properties, high crystallinity and regular structure, and high tensile strength.
TYPES OF SURFACE TREATMENT PROCESSES
Plastic products after injection molding often require surface treatment to improve appearance, increase durability or give specific functionality. The following are some commonly used injection molding surface treatment processes:
Polishing
Polishing is a method of obtaining a smooth surface by physically removing protruding parts from the surface of a material. Common tools include oilstone strips, wool wheels, sandpaper, etc. Polishing can significantly improve the surface glossiness and flatness of the product.
Spray Coating
Spray paint or other coatings on the surface of plastic to change its color, increase its protective layer, or provide special effects.
Printing
Including screen printing, transfer printing, hot stamping, etc., used to add text, logos or patterns on the surface of plastic products.
Sand Blasting
Use compressed air to spray abrasive at high speed onto the surface of plastic products to change their texture or clean the surface. Sandblasting can make the surface matte or have a rough texture
TOLERANCE AND DIMENSIONAL ACCURACY
The tolerance and dimensional accuracy of injection molds are important factors in ensuring the quality and consistency of injection molded products. In the design and manufacturing process of injection molds, it is necessary to strictly control tolerances and precision in multiple aspects to ensure that the quality of the final product meets the requirements.
Linear dimensional tolerance
The linear dimensional tolerance range is ± 0.1% to ± 0.2%
Angle tolerance
The angle tolerance is ± 0.2 ° to ± 0.3 °
Surface roughness
The surface roughness is Ra ≤ 1.2 μm
Dimensional tolerance
Depending on the nominal size of the injection molded part, the tolerance range will vary.
For sizes from 1 mm to 3 mm, tolerances are ±0.06 mm for the precision grade and ±0.08 mm for the ordinary grade.
For dimensions ranging from 3 mm to 6 mm, the precision grade tolerance is ± 0.08 mm, while the ordinary grade tolerance is ± 0.09 mm

WORKING PRINCIPLE, ADVANTAGES AND APPLICATIONS
1. What is injection molding?
Injection molding is a common industrial manufacturing process mainly used for producing large quantities and high-precision plastic products. This process involves injecting plastic heated to a molten state into a mold, allowing the plastic to cool and harden, and then removing the finished parts from the mold.
2. Injection molding, as a widely used plastic processing technology, has many significant advantages. The following are the main advantages of injection molding:
Efficient mass production
Injection molding is very suitable for mass production and can quickly produce a large number of identical products.The production cycle is short, and once the mold is ready, it can be continuously produced.
Highly automated
The injection molding process is highly automated, reducing manual intervention and improving production efficiency.The high level of automation means that the production process is more stable and reliable.
Cost effectiveness
When producing in large quantities, the cost per unit is relatively low.Although the initial mold cost is high, the unit cost will gradually decrease as production increases.
Dimensional stability
Injection molding can provide good dimensional accuracy and tolerance control.It can produce parts with consistent dimensions, suitable for applications that require high-precision matching.
3. Application
Injection molding is a very common and widely used plastic processing method, which can produce various complex shaped and precisely sized plastic products. The following are common applications of injection molding in different fields:
Automotive industry
Interior parts, dashboard, seatbelt buckles, air conditioning vents, lampshades, etc.
Medical equipment
Disposable syringes, blood dialysis equipment components, electrocardiograph components, and other medical supplies.
Quality control includes the use of appropriate materials, precise mold design, correct molding parameter settings, and finished product inspection. Modern injection molding machines are typically equipped with automated quality control systems to ensure that every product meets standards.
The injection molding cycle time depends on multiple factors, including product size, thickness, mold temperature, cooling time, etc. Generally speaking, the cycle time of simple products may only be a few seconds, while the cycle time of complex products may be as long as a few minutes.
The cost of molds varies depending on the complexity of the mold, the required materials, manufacturing processes, and production quantities. Simple molds may cost only a few thousand yuan, while complex high-precision molds may require hundreds of thousands or even more.
The material selection depends on the final use of the product, the required physical properties (such as heat resistance, strength, toughness), appearance requirements (such as transparency, color), and budget. Injection molding service providers can help you choose the most suitable materials based on these factors.
In the early stages of design, you should consider factors such as the geometric shape, size, and thickness of the product. Complex geometric shapes may require finer mold design. You can consult professional injection molding service providers who can provide improvement suggestions based on your design.
