How to Work
From the moment your injection mold order is confirmed, we follow a standardized procedure to ensure transparency and smooth transitions at every step. This process keeps both our team and customers fully informed on the progress, guaranteeing that each phase is executed efficiently. Here’s how we begin and complete your injection mold project:
1
Confirm drawings, materials, and requirements. Once the quotation is approved, we sign the order and start the project.
2
We conduct DFM analysis and complete mold design. After client approval, we proceed to mold fabrication.
3
We carry out steel machining, CNC, EDM, polishing, and mold assembly, progressing each step on schedule.
4
We carry out the first mold trial (T1) to verify dimensions and appearance, and provide samples with a trial report. Multiple iterations (T2/T3) are performed as needed until the sample meets all requirements.
5
We make necessary adjustments based on trial feedback, ensuring the sample meets all requirements. Once quality inspections are passed, we provide the client with the final confirmation before proceeding to mass production.
6
After receiving final approval, we start mass production, ensuring consistency in quality and maintaining production schedules. Each batch is carefully monitored to meet client specifications, with regular progress checks to ensure no delays.
7
During and after production, we perform rigorous quality control checks to ensure that all products meet the highest standards. Any defects or issues are immediately addressed and resolved before products are approved for shipment.
8
Once quality inspection is completed and the products are approved, we package the products securely to prevent any damage during transportation. We arrange for timely shipping according to the client’s specifications and preferences.
9
We offer a lifetime warranty for injection molds used in-house. We are committed to maintaining consistent quality.

Mold Making FAQs
Q1: What is a plastic injection mold?
A plastic injection mold is a precision-engineered tool used to shape molten plastic into final products. It enables consistent, high-accuracy production and is widely used in industries such as medical, automotive, electronics, consumer goods, aerospace, and more.
Q2: Who owns the mold?
You do. At Xinjuexin, we build the mold for you, and you retain full ownership. Once production is complete, we can store the mold at our facility or ship it to your location upon request. If needed, our engineers will assist you in checking compatibility with your machines.
Q3: What makes injection molds complex to produce?
Injection molds require a high level of precision, material durability, and custom engineering. Each mold is designed and manufactured to meet specific product requirements, including tolerances, surface finish, and cycle life. The process involves advanced equipment, experienced technicians, and close quality control at every stage.
Q4: How can I request a quote?
We usually provide a quotation within 48 working hours after receiving full technical details. Please include the following with your inquiry:
- 3D files (.STEP preferred) and 2D drawings
- Material specification
- Surface finish requirement
- Estimated quantity (batch/month/year)
- Special instructions (e.g., packaging, labeling, delivery terms)
Q5: What if I don’t have a 3D drawing?
If no digital design is available, you can send us a sample or sketch with basic dimensions (length, width, height). We will support you with drawing development and provide CAD or 3D files after confirming the order.
Q6: What is the typical lead time?
Mold fabrication usually takes 4 to 7 weeks, depending on part size and complexity.
Mass production lead time ranges from 1 to 3 weeks, depending on the volume.
Q7: How do you ensure mold quality before shipment?
If you can’t arrange a factory visit or third-party inspection, our team will perform full in-house inspection and share:
- Tool testing parameters and videos
- T1 sample photos
- Dimensional inspection reports
Q8: What surface finishes are available?
We offer a wide range of texture and surface finish options including SPI, VDI, MoldTech, Yick Sang, laser texturing, or custom finishes tailored to your product requirements.
Q9: How are molds packed for shipment?
Molds are protected using a three-step method:
- Apply anti-rust oil to all surfaces
- Wrap the mold with moisture-proof plastic film
- Secure the mold in a reinforced wooden crate to prevent movement during transport
