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

Does Henglv provide a no-obligations estimate for my injection molding project?
Absolutely. As long as you are able to supply project requirements and part specifications, Henglv is happy to provide a no-obligation quotation.

Once I have a mold, can I reorder from it?
Of course! Henglv 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 Henglv charge an inventory fee on my molds?
Henglv 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, HengLv will ship/destroy the mold at the customer's direction.

Does Henglv provide DFM on my part design before I place an order?
We do! Not only are you able to access your DFM through the Henglv platform, but you will receive 3D visualization of the DFM feedback and be able to comment on, annotate, and discuss this feedback with a HengLv technical project lead. All of this happens before you place your order.

Does Henglv charge for DFM feedback?
We believe in getting our customers the best possible parts the first time. Therefore, Henglv 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 Henglv build quick turn Aluminum molds?
