Injection Molded Plastic Parts

Rapid Prototyping: The shorter cycle time of injection molding is particularly suitable for batch production, and can complete the manufacture of large quantities of products in a short period.
The High Degree of Automation: automated production lines can significantly improve efficiency and reduce labor costs.
Low Unit Cost: For mass production, the unit cost is significantly reduced.
High Material Utilization: less material waste in the plastic injection molding process, and the trimmings can be recycled.

High Degree of Reproduction: enables the production of products with complex shapes and precise dimensions, such as parts with detailed features and internal structures.
One-piece Molding: enables integrated molding of parts, reducing assembly and subsequent processing steps.
High Precision: Injection molded products have high dimensional accuracy and consistency, making them suitable for manufacturing high-quality industrial parts and consumer products.

Raw Material Selection: A wide range of plastic materials can be processed (e.g. ABS, PP, PE, PC, etc.), even reinforced plastics with glass fiber and filler added.
Color Options: Multiple material combinations (two-color injection molding or multi-material injection molding) can be achieved for the same product.
Surface Options: injection molding can achieve a variety of surface effects, such as smooth, textured, or matte finishes, without additional processing.

Expensive Mold Cost: mold design and manufacturing costs are high, especially complex molds or multi-cavity molds.
Large investment in equipment: injection molding machines and other equipment are expensive, especially high-precision equipment.
Long Mold Cycle: Mold manufacturing requires a certain period, which may extend the product development time.
Product Suitability Testing: the product design and mold must be highly compatible, and require repeated verification and optimization in the early stage.

Lack of Material Clarity: Not all materials are suitable for injection molding (e.g., certain thermoset plastics and high-temperature materials).
Deformation Risk: the process is demanding for thin-walled and large-sized products, which may lead to warping, shrinkage, and other defects.
Processing Parameter Risk: Influenced by process parameters (e.g. temperature, pressure, cooling speed), the process is prone to problems such as bubbles, lack of material, warpage, etc., and requires strict control of process conditions.
Risk of Mold Design: Improper mold design may lead to shorter mold life or lower product quality.

High-volume Dependence: Not suitable for low-volume production, as the cost of molds can lead to high unit costs when spread over a small number of products.
Raw Material Risks: Some plastic materials are non-biodegradable and the resulting waste may hurt the environment.
Environmental Risk: The injection molding process may involve chemical additives or the emission of hazardous substances.
