丝网印刷，又称丝网印刷或丝网印刷，是一种用于在塑料零件上添加高质量图形或文字的后处理技术。 丝网印刷通常用于为各种应用制作铭牌、标签和装饰元素。 它是提高注塑成型塑料零件美观性和功能性的有效方法。
Silk screening, also known as screen printing or serigraphy, is a post-processing technique used to add high-quality graphics or text to plastic parts. Silk screening is commonly used to create nameplates, labels, and decorative elements for various applications. It is an effective way to enhance the aesthetics and functionality of injection-molded plastic parts.
UV coating is a method of using ultraviolet light to cure or dry coating material on various materials, including plastics, resulting in a durable, glossy finish. For injection molding with UV coating, it’s important to use compatible materials to accommodate the coating application method.
We can provide plastic parts assembly services according to customer needs, which means we can assemble plastic parts that match each other. However, we do not offer assembly services for electrical products or final finished products such as electrical components.
Shipping by ship to the USA takes about three weeks and to Europe about five weeks. If your part is more minor, we can ship it by air, in which case it arrives in about four days.
Once the plastic products are assembled, they will occupy less space, making it easier to ship them. However, due to the extended transportation time, we will implement protective measures for the products before shipment to guarantee their integrity. Communicating your specific requirements during the quotation period is essential for us to accurately assess the final unit price of the product.
We have 60T-500T injection molding machines, which accommodate up to 825mm 825mm 820mm (lengthwidththickness) molds. Our CNC machining centers can achieve ±0.015mm machining accuracy for the molds and conduct online testing of the accuracy after the machining is completed to ensure that it meets the standard.
Making an injection mold usually takes 6 to 8 weeks, depending on the part’s complexity. Once the mold is ready, the mold is tested, and the first out-of-stock (FOT), also known as T1 (for testing), is the first set of plastic parts sent to the customer. Then, the customer will give us feedback on the problem points after the trial run. We will make some minor mold adjustments based on the customer’s problem points and then send the new samples to the customer. The whole modification usually takes about two weeks. When the product improvement is completed, and the customer approves the entire set of samples, the mold will be validated for small-batch trial production.
Our regular order of plastic parts is 500-1000pcs. Of course, the first small batch of trial production in the early stage can be 100-500 pcs, but the small batch of trial production will be charged some shipping costs, which is based on the actual situation of the two sides to negotiate.
We have our in-house mold repair capability and will repair the molds until they are produced smoothly. If molds need to be rectified, we will create a data report and confirm with the customer before making any modifications.
