ABS


ABS or Acrylonitrile Butadiene Styrene is a thermoplastic polymer that is produced using emulsion. It is an incredibly versatile material, known for its excellent resistance to corrosive chemicals, making it useful in various applications such as automotive parts, toys, and electronic housings.

 ABS is also easy to machine and has a relatively low melting temperature, which means it can be molded and shaped with ease. Its high impact resistance makes it ideal for use in products that may undergo significant stress or force. Due to its unique properties, ABS is widely used in many industries worldwide.

Injection Molding FAQs
Is injection molding a good option for prototyping?

Injection molding could absolutely be used for prototyping, but it depends on the project requirements. Typically, for projects that require less than 10 prototypes, injection molding may not be the most cost-effective option. We are happy to meet with you to discuss your needs and help determine if injection molding is the correct process for you.


What is the minimum order quantity for injection molding?

JingYu is happy to offer you injection molding services with NO minimum order quantity.


Does JingYu provide a no-obligations estimate for my injection molding project?

Absolutely. As long as you are able to supply project requirements and part specifications, JingYu is happy to provide a no-obligation quotation.


Once I have a mold, can I reorder from it?

Of course! JingYu will maintain your mold for 2 years after your most recent order and allow you to re-order parts for the duration of the mold life.


Does JingYu charge an inventory fee on my molds?

JingYu does not charge any inventory fees for holding your molds, as long as you order off of the mold within 2 years. After 2 years of inactivity, JingYu will ship/destroy the mold at the customer's direction.


Does JingYu provide DFM on my part design before I place an order?

We do! Not only are you able to access your DFM through theJingYu platform, but you will receive 3D visualization of the DFM feedback and be able to comment on, annotate, and discuss this feedback with a JingYu technical project lead. All of this happens before you place your order.


Does JingYu charge for DFM feedback?

We believe in getting our customers the best possible parts the first time. Therefore, JingYu does not charge for DFM and we ensure that you have all of the assurances you need before you place your injection molding order.


Does JingYu build quick turn Aluminum molds?

JingYu has the ability to build both aluminum and steel molds.
