Description: In the injection molding process, molten PVC material is injected into the mold under high pressure to form a toy.
Method: The molten PVC is injected into the mold cavity and allowed to cool and solidify to form the shape of the toy.
Application: Injection molding is a widely used method for mass production of PVC toys with stable quality and high efficiency. It is suitable for mass production needs.[/caption]

Main differences:

Drip glue process: Relying on pouring liquid PVC into the mold, it is suitable for complex designs.

Injection molding process: Molten PVC is injected into the mold under pressure, which is suitable for mass production of PVC toys with stable quality.

In short, the drip glue process is to pour liquid PVC into the mold, while the injection molding process is to inject molten PVC into the mold under pressure. Each method has its own advantages and should be selected according to the specific requirements of the PVC toys produced.

Advantages and disadvantages of glue dripping process:

Advantages:

1. Flexible operation: The glue dripping process is flexible in operation. It can be well completed for products with complex shapes, fine and small shapes or products with special requirements, such as small crafts, badges, etc.
2. Relatively low cost:The equipment and material costs of the glue dripping process are relatively low, and no large professional equipment is required. For small-scale production, it is a more economical and affordable choice.
3. Strong repairability:If a small number of defects or errors occur during the glue dripping process, they can be corrected and adjusted before the glue is completely cured, which has a certain degree of repairability.

Disadvantages:

1. Low production efficiency: The glue dripping process is usually manually operated or uses simple glue dripping equipment. The production speed is relatively slow, and it is difficult to achieve large-scale and efficient production. It is not suitable for the production needs of large-scale orders.
2. Long curing time:It takes a certain amount of time for the glue to cure, especially at room temperature, the curing speed is slow, and it may take 2-6 hours or even longer to fully cure, which will affect the production cycle
3. Limited strength: Compared with the injection molding process, the strength of the glue products is relatively low, and may not be suitable for some application scenarios with high strength requirements.

Advantages and disadvantages of injection molding:

Advantages

1. High production efficiency: Injection molding is a highly automated production method that can achieve fast and continuous production. It can produce a large number of products in a short time and is suitable for large-scale production and large-volume orders.
2. High dimensional accuracy: The injection molding machine can produce products with very high dimensional accuracy and good dimensional stability through precise control and high precision of the mold, which can meet the application scenarios with strict requirements on product size.
3. Complex structures can be realized: The injection molding process can form products with complex structures at one time, such as products with raised parts, ribs, threads and other structures, without the need for subsequent processing and assembly, reducing production costs and production cycles.

Disadvantages:

1. High mold cost:The injection molding process requires the production of special molds, and the design, manufacturing and debugging costs of the molds are high, especially for products with complex shapes. The mold cost may account for 30%-40% of the total cost. Moreover, the mold has a limited service life and needs to be replaced and maintained regularly, which increases the production cost.
2. Trouble changing molds: If there are many styles of products, the molds need to be replaced frequently. The mold changing process is more complicated, which takes a long time and manpower, affecting production efficiency.
3. Heavier weight: Compared with glue-dripping products, injection molding products are harder, so they are heavier than glue-dripping products.

How to differentiate between drip and injection moulding

• Injection molding productsare made by disassembling parts, grinding and polishing, printing, spraying and assembly. The whole product is very tightly combined. The whole detail is done very well. The interfaces are closely matched, and the product restoration is very high. After getting it in hand, the product is relatively hard and relatively heavy.
• The biggest feature of the drip glue processis double-sided pressing and high-temperature molding. So there will be a double-sided mold line. The whole product is composed of a split mold phase diagram. The surface will be convex. If it is flat, there will be a color separation line between the colors. It is divided by the mold phase. This is the biggest feature. After getting it in your hand, the whole product will be softer and relatively lighter.

Examples of PVC toy products suitable for the glue dripping process

Small decorative doll ornaments

Product features: These dolls are usually small in size, about 5-10 cm in height, with exquisite and complex shapes, and may have fine textures, lace-like patterns or inlay effects. For example, some doll ornaments with a retro style have exquisite patterns on their clothes and delicate curls on their hair.

Reason: The glue dripping process can accurately fill these fine textures and patterns, making the details of the product more vivid. Since the product is not large in size, the glue dripping operation is relatively convenient. The glue can be slowly dripped into the mold to allow the glue to fully cover and fill the parts that need to show details. Moreover, for this type of decorative products, the smooth, transparent or glossy surface effect formed by the glue dripping can enhance the beauty of the product and enhance its visual appeal as a decoration.

Examples of PVC toy products suitable for injection molding

Standard-shaped toy figures produced in large quantities

Product features: Like classic superhero figures or anime character figures, these figures are generally 10-20 cm tall, relatively regular in shape, and have uniform design standards. They need to be mass-produced to meet market demand. For example, a popular anime figure may need to be produced in tens of thousands of pieces.

Reason: The injection molding process is extremely efficient in mass production. Through the designed mold, PVC material can be quickly and accurately injected into the mold cavity to form the main structure of the figure in one go. The injection mold can ensure the dimensional accuracy and shape consistency of each product, which is very suitable for this kind of product with high requirements for modeling accuracy and standardization. In addition, the injection molding process can realize automated production, greatly reducing production costs, increasing production speed, and meeting the needs of mass production.
