CNMOULDING-injection mold company

 CNMOULDING-injection mold company offers a plastic injection molding service and specializes in various plastic molds. automotive, home appliances, electronics, as well as general industrial OEM applications. Our company covers an area of more than 2000 square meters workshop, surrounded by convenient transportation. At present, our group reaches more than 100 employees and capital assets to more than 8 million RMB. Our capacity is 40-50 sets of mold per month.

CNMOULDING-injection mold company's mission is to be a professional, trustworthy, and creative toolmaker and injection molding supplier. We always keep the Layout at the top level and introduce a modernized management system. Go in for zero default. Make sure quality and techniques are in the highest way. Therefore, we dedicate ourselves to making innovation and progress and continue to be your better partner. Enhance our technology and accumulate experience in mold building, injection molding, print, paint, etc.



1, We provide direct factory prices and make costs transparent.

As you know there are more than 5000 trading companies in China, but some of them concealed their property very well. It is hard to tell a foreigner. normally they will make a profit of 30%.so we show the detailed cost on our website, Most traders can’t quote the price at this level. But these prices are a normal price for us and have a proper profit.

2, We focus on providing a one-stop service for small and medium-sized companies.

We are a middle size mold making and injection molding company. It is also one reason for the good price. We don’t need to pay the huge administration fee compared to the big factory. We got an ISO9001-2008 certificate, which ensures our quality same as the big factory. As everyone knows china mold is much cheaper than in the USA or Europe but injection molding will be more expensive because the resin price in China is 50% higher or double. But if you only produce 1,000-50,000 pcs. then China will have a big advantage. Moreover, we can make print, paint, and assembly in the house.it also saves a lot!

3, Our Sales Manager has rich experience in engineering.

Most of the companies will arrange sales girls to contact customers, they are lack mold knowledge, just transfer e-mail and said some holiday words but will get good commission(3-5% total price. Of course, the cost will be calculated in their quotation). our Sales Manager will handle the job for both the sales manager and project manager. It will make sure our professional service gets through the whole process and the communication is more efficient.

I think they are the biggest treasure of our company, their experience, and hard work will be guarantee high-quality mold at a reasonable price.

The concept of plastic injection molding

Plastic Injection molding is used to produce many things such as wire spools, packages and bowls, bottle caps, automotive parts, toys, optics, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today. Injection molding is the most common modern method of manufacturing parts; it is ideal for producing high volumes of the same object.

Injection molding uses a ram or screw-type plunger to force molten plastic material into a mold cavity; this solidifies into a shape that has conformed to the contour of the mold.

Our injection shop:

CNMOULDING is one of the famous plastic injection molding companies in China. Our injection molding shop is equipped with 20 sets of high-precision injection molding machines ranging from 50ton to 650 tons, they are mostly imported from Taiwan or Japan. Our injection shop runs 24 hours a day, 7 days a week automatically production services.

We are experienced with various plastic products for automotive, medication, lighting, sports equipment, home appliance, and agriculture. credited an ISO9001-2008 certificate since 2004, also has 5 IPQC people watch the production and check the quality within 24 hours, it makes sure our production keeps a stable quality, in the past 15 years, our company already win a good reputation with stable quality and reasonable price. keep a good business relationship with 50 customers, especially from the USA and Europe

In order to produce save costs and time in the process of plastic injection molding and improve the production efficiency of the injection mold. Mold manufacturers increasing the use of new materials and new technologies. And these new materials and new technologies to a certain extent, represent plastic injection mold manufacturing as a new trend.

Precision Redefined: The Advantages of Our CNC Machining Center with ATC

 Our new CNC Machining Center, equipped with an Automatic Tool Changer (ATC), represents a significant leap forward in manufacturing capability. The true precision advantage of the ATC lies not just in speed, but in its ability to fundamentally enhance process stability and guarantee superior final part accuracy.



Here are the core benefits driving this new level of precision:

1. Eliminating Human Error for Unwavering Consistency

Traditional Manual ChangeATC Advantage (Automated)
Inconsistency: Manual handling introduces variability—uneven tightening force, potential contamination, or operator fatigue—all leading to tool runout and inaccuracy.Repeatability: The ATC executes every change with identical, programmed motions. It consistently cleans the taper, grips, and locks the tool, ensuring perfect, repeatable positioning.
Impact: Random human errors are eliminated, guaranteeing superior tool-holding rigidity and minimal runout, which is critical for tight tolerances.

2. Enabling "Complete Machining in a Single Setup"

Manual processes force interruptions for tool changes, introducing potential cumulative errors from thermal drift or workpiece shifting.

The ATC overcomes this bottleneck by completing all required operations (milling, drilling, tapping) in one continuous, automated cycle without removing the part. This is critical because it:

  • Maintains a Single Datum: The workpiece remains fixed to a single zero point, preventing the cumulative errors associated with re-fixturing.

  • Guarantees Geometric Integrity: It reliably ensures high positional accuracy and tight geometric relationships between all features (holes, slots, surfaces) on the finished component.

3. Ensuring Flawless Batch Consistency and Process Stability

For batch production, the ATC ensures the entire machining process, including the tool changes, is perfectly repeatable from the first part to the thousandth. This unparalleled process stability removes human variables, guaranteeing high consistency in dimensions and tolerances across the entire production run.

4. Supporting Optimized and Adaptive Machining Strategies

The ATC makes advanced strategies practical:

  • Dedicated Tooling: It allows for dedicated "roughing" and "finishing" tools. The finishing tool remains sharp and unaffected by the wear of the roughing process, directly resulting in a better surface finish and tighter tolerances.

  • Adaptive Control: It enables the use of in-process probing and automatic tool compensation, facilitating continuous adaptive control for real-time accuracy adjustments.


Summary: Our Precision Commitment

Key AdvantageBenefit to Your Project
High RepeatabilityConsistent tool positioning and minimal runout.
Low Error Accumulation"One setup" machining prevents error stacking.
High Process StabilityHuman variables are removed from the production cycle.
Superior Process CapabilityEnables optimal dedicated finishing strategies.

This new investment ensures we can provide our customers with more precise and reliable mold manufacturing services than ever before.
