PVC Keychain Making Machine is a special drop-molding equipment specially designed for the molding of PVC material keychains. It belongs to the category of PVC drop-molding equipment. It relies on the drop-molding process, using PVC paste resin as the core raw material, with auxiliary materials such as plasticizers, color pastes, and stabilizers. Through core processes such as precise temperature control, three-dimensional glue dispensing, vacuum defoaming, heating and solidification, and cooling and demoulding, it is an automated or semi-automatic special equipment for three-dimensional modeling and multi-color superposition molding of keychains. What machines are used to make PVC soft rubber keychains?
Soft PVC keychains are quite common in daily life. We can see all kinds of colorful and uniquely shaped soft rubber keychains in shopping malls, and some even have luminous and glitter effects.
Dispensing machine/Dropping machine: A dimensional automatic dispensing machine is used to drop different colors of PVC raw materials into the mold according to the pattern.
Oven/Baking machine: After dispensing, the PVC glue is baked and cured. There are usually two baking processes: one for the surface layer (shorter time), and one for the base layer (longer time).
CNC engraving machine: Used to engrave molds. Commonly used molds are made of aluminum or copper, and are engraved according to the product design; if the factory is not large, it is recommended to find a mold factory to make the molds, as the machine costs are high and the operation is difficult, making it unsuitable for beginners.
What are some common problems with PVC resin keychains?
1. Bubbles in the product: This is usually due to a large number of bubbles generated during the mixing of raw materials, and insufficient or no vacuum treatment of the raw materials, resulting in incomplete removal of bubbles; it may also be due to dead corners during machine dispensing, causing the PVC raw material to not flow properly. After dispensing, workers can appropriately vibrate the mold to expel the gas.
2. Keychains made of soft PVC are prone to yellowing. Over time, the product is prone to oxidation, especially the white parts. This problem is usually improved by adjusting the raw material formula, adding anti-yellowing agents and antioxidants.
Which is better for making keychains, PVC or silicone?
There is no absolute better or worse between these two materials; both have their advantages and disadvantages.
PVC material is harder and easier to break, while silicone is softer and has a better feel.
PVC material is more wear-resistant and has richer colors, while silicone material is more heat-resistant and resistant to yellowing, and does not break easily even with repeated bending.
Silicone material is more environmentally friendly, so if environmental requirements are high, silicone material is preferred.
