If no 2D drawing is provided, MIC-ZG produces parts according to ISO 2768 M standard. With 2D drawing, we can reach tolerance as tight as +/- 0.01 mm.
At MIC-ZG, we offer various injection molding services which includes quick tooling, family molds, multi-cavity molds, over molding, etc., for your manufacturing needs. Each service is based on various manufacturing standards highlighted below:
| Part size (mm) | Production tooling | Quick tooling |
| 1~22 | ±0.06~0.09 | ±0.08~0.13 |
| 22~70 | ±0.11~0.17 | ±0.14~0.24 |
| 70~160 | ±0.20~0.29 | ±0.30~0.43 |
| 160~250 | ±0.36~0.44 | ±0.51~0.68 |

| 315~500 | ±0.70~0.90 | ±1.08~1.38 |
| 500~1000 | ±1.20~1.90 | ±1.83~2.90 |
| 1000~1400 | ±2.30~2.65 | ±3.50~4.05 |
| 1400~2000 | ±3.05~3.80 | ±4.65~5.80 |
We have experience and the right sheet metal fabrication services necessary to bring that YOUR idea to life. This includes services like high tolerance and wide thickness range laser cutting, bending capabilities, and other post-processing options.
| Dimension detail | Tolerance |
| Edge to edge, single surface | +/- 0.005 inch |
| Edge to hole, single surface | +/- 0.005 inch |
| Hole to hole, single surface | +/- 0.005 inch |
| Bend to edge / hole, single surface | +/- 0.010 inch |
| Edge to feature, multiple surface | +/- 0.030 inch |
| Over formed part, multiple surface | +/- 0.030 inch |
| Bend angle | +/- 1° |
By default, sharp edges will be broken and deburred. For any critical edges that must be left sharp, please note and specify in your drawing.
3D Printing is the best service if you want the best functional parts prototyping. At MIC-ZG, we provide you with the best technologies in 3D printing such as FDM, SLA, SLS, Polyjet. For other technologies associated kindly contact us.
| Process | Min. wall thickness | Layer height | Max. build size | Tolerance |
| SLA | 1.0 mm | 50 – 100 μm | 250 * 250 * 250 mm | ± 0.5% with a lower limit of ± 0.5 mm (± 0.020″) |
| SLS | 1.0 mm | 100 μm | 420 * 500 * 420 mm | ± 0.5% with a lower limit of ± 0.15 mm (± 0.006″) |
| FDM | 1.0 mm | 100 – 300 μm | 500 * 500 * 500 mm | ± 0.3% with a lower limit of ± 0.3 mm (± 0.012″) |
Learn the most stringent inspection methods we applies over the course of the entire manufacturing process..
Before the production stage begins, our engineering team performs a technical assessment on your parts design. We will give professional advice from the point of view of material, structure, process and practicality.Help you to complete the final design and order as soon as possible.
All materials we choose are based on customer requirements. Of course, when you are hesitant about which material to choose, you can consider telling us your use and needs, and we will recommend the most appropriate material to help you complete your design from a professional point of view.
In precision machining, it is important that materials being worked on is always at the right position. With on-site inspection system, positions are examined automatically, and adjustments are made accordingly. Using on-site inspection system further helps avoids issues at the early stage, saving cost and time.
At MIC-ZG, we strictly obey the ISO9001:2015 requirements. The quality control staff conducts routine inspections for all parts that are being produced every 2 hours. This further prevents risks from happening.
MIC-ZG has a very complete production and quality control system. Fast delivery of customized products and visual production services. They will send the whole process of development and production to customers in real time through pictures and videos, so that customers can know the status of their products at any time. They send the finished product to the customer in written form, and professionally like a quality inspection report.
We fully consider the wishes of buyers, according to the needs of buyers to provide personalized packaging. If personalized packaging is not required, the basic packaging we provide : 1. wrapping paper 2. EPE 3. foam 4. paper/wooden box are applied during the packaging process, ensuring that we deliver the most high-quality and beautiful parts to you.
We use the Coordinate Measuring Machine (CMM) for dimensional inspection of parts produced. CMMs can measure physical parts of an object by sensing and collecting points along its surface using a probe. It is especially suitable for parts with complex geometries.
On completing the manufacturing process, we use optical comparator/ a projector to inspect the dimension of the components. This projector is ideal for dimensional check as it precisely measures the part’s dimensions and compare them to the original CAD model. Any inconsistencies detected by the projector are alerted in a detailed inspection report.
We employ X-Ray Fluorescence (XRF) analysis for checking the material quality. The XRF analyzer uses short X-rays and gamma rays to determine the elemental composition of metals, plastics and other materials, to inspect the quality of the materials.
Quality reports
For every order on our platform, we can provide a full list of quality reports according to customers’ request. Including but not limited to:
Inspection report
Full dimensional report
Material test report
Certifications
As a decade-experience on-demand manufacturing company, we provide most commonly needed certifications, including but not limited to:
ISO 9001:2015
ROHS
REACH
For low-volume injection molding and CNC machining orders exceed 50 units or 5000 USD in total price, first article inspection is available on request. The process goes like below:
The customer request first article inspection for a project that meets our FAI requirements.
MIC-ZG reviews on the project and contacts customer for detail information.
The customer signs the FAI agreement provided by MIC-ZG and agree on our Terms and Conditions.
MIC-ZG produce sample parts according to FAI agreement and deliver to the customer.
The customer receives and examines the parts, inform MIC-ZG if full-scale production may begin.
The full-scale production starts and finishes production within lead time.
At MIC-ZG, it is our aim to deliver high quality parts that matches your requirements and expectations. However, if your order fails to meet your specifications, you will be covered with our Rework and Refund Policy.
Kindly get in touch with us within five business days of receiving your order, and we will resolve the problem rapidly within 1-3 business days.
