Brand image, cartoon patterns, artistic text, etc. can be integrated into the design according to customer needs, making keychains a fashionable accessory.
Additional practical features: To enhance the practicality of the keychain, some additional features can be added, such as a mini bottle opener, nail clipper, small mirror, LED light, compass, etc. These features not only increase the frequency of keychain usage, but also deepen users' impression of the brand or event during use.
4. Information Content
The information content on the customized plastic keychain should be concise, clear, highlight key points, and coordinated with the overall design:
Brand related information: including brand logo, brand name, brand slogan, official website, contact phone number, etc. The layout of this information should be reasonable, ensuring that it is clearly visible within the limited space of the keychain, which helps to increase the brand's exposure and visibility.
Event Information: For event commemorative keychains, information such as the event name, theme, time, and location can be printed to make the keychain a permanent memory of the event, carrying the memories of the participants.
Personalized information: For personal customization or gift customization, personalized content such as name, blessings, commemorative date, exclusive number, etc. can be added to make the keychain more unique and emotionally valuable, becoming a carrier for conveying feelings.
The presentation of information should match the shape and material of the keychain to avoid overcrowding and affecting the overall aesthetics.
2、 Process Description
1. Printing process
Printing technology is a key step in showcasing the design charm of customized plastic keychains. Common printing techniques include:
Screen printing: suitable for flat or curved plastic keychains, capable of printing clear and vivid patterns and text on their surface. Ink has strong adhesion, good friction and water resistance, is not easy to fade, and has low cost. It is suitable for mass production, especially for printing simple logos and text.
Pad printing process: For plastic keychains with irregular, curved, or uneven surfaces, the pad printing process can adapt well. It transfers the pattern from the printing plate to the surface of the keychain through a silicone print head, achieving multi-color overlay printing with high printing accuracy and presenting complex pattern details. It is widely used in the printing of various shaped keychains.
UV printing: Using UV ink, it can quickly cure through ultraviolet radiation and form a hard coating on the surface of plastic keychains. UV printing has high color saturation, strong three-dimensional pattern, good adhesion, and excellent scratch resistance and weather resistance. It can achieve high-precision color printing, suitable for personalized customization and small batch production, and can meet the printing needs of complex patterns.
Heat transfer printing process: First, print the pattern on transfer paper, and then transfer the pattern to the surface of the plastic keychain through high temperature and high pressure. This process is suitable for printing patterns with rich colors and diverse layers, especially on curved and irregular keychains, which can achieve good results. The printed patterns are brightly colored and durable.
2. Production process
Mold making: Make molds based on the keychain design drawings determined by the customer, and the accuracy of the molds directly affects the molding quality of the keychain. Adopting advanced mold processing equipment to ensure accurate size and smooth surface of the mold, it can accurately present the shape and details of the keychain. For keychains with complex shapes, it may be necessary to make them separately and then combine them.
Injection molding: After heating and melting the plastic raw materials, they are injected into the pre made mold, cooled and solidified, and then demolded to form the blank of the keychain. During the injection molding process, it is necessary to strictly control parameters such as temperature, pressure, and injection speed to ensure that the keychain is fully formed, without bubbles or defects, and that the dimensions meet the design requirements.
Subsequent processing: After injection molding, the keychain needs to undergo a series of subsequent processing treatments, including removing burrs, polishing and grinding, to make the surface smooth and flat; Process printing according to design requirements to present patterns and text clearly; Install hanging rings, buckles, and other accessories to ensure a secure connection; For keychains that require special effects, electroplating, painting, dripping, and other treatments can be carried out to enhance their texture and aesthetics.
After each batch of customized plastic keychains is produced, they undergo strict quality testing, including appearance quality (no scratches, no deformation, uniform color), printing quality (clear patterns, no missing prints, strong adhesion), functional quality (secure hanging buckle, normal additional functions), etc., to ensure that the product meets customer requirements and provide customers with high-quality customized plastic keychains.
