Plastic injection molding is the preferred process for manufacturing plastic parts. Injection molds are used to create many things such as electronic housings, containers, bottle caps, automotive interiors, pocket combs, and most other plastic products available today. Plastic injection molds are ideal for producing high volumes of plastic parts. Due to the ability to make multi-cavity injection molded parts. Where multiple parts are made with one cycle. Some advantages of injection molding are high tolerances, repeatability. A  wide range of material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding. Some disadvantages of this process include an expensive tooling investment and the need to prototype. Some custom complex parts may encounter problems during the injection molding process such as warp or surface defects. Therefore, injection molded parts must be designed with careful molding consideration.

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 Change	ATC 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 Advantage	Benefit to Your Project
High Repeatability	Consistent tool positioning and minimal runout.
Low Error Accumulation	"One setup" machining prevents error stacking.
High Process Stability	Human variables are removed from the production cycle.
Superior Process Capability	Enables optimal dedicated finishing strategies.

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

Post-processing technology of injection products

 

Post-processing technology of injection products

For printing on the surface of the plastic products, printing or when the pattern. there are several methods.

1, Stencil printing of this method is the most common and also the most one method; they are generally suitable for flat or curvature of the small print.

2, The principle of curved surface printing flexography printing ink is first placed within the text or logo engraved gravure, then copy the text or images onto a surface. The surface will re-use the text or pattern is transferred to the surface of the molded product. And finally through an ultraviolet light irradiation heat treatment or the like so that the ink is cured.

Skim A. molded products

1. molded product surface treatment (when necessary)
2. Printing
3. curing inks
4. applying post-processing such as excessive (if necessary)

injection parts processing-Printing Process

1. Gravure ink into the.
2. Scrape off the excess ink.
3. Extruded surfaces are made of ink.
4. The surface of the ink transferred to the surface of the molded article.
5. Cleaning surfaces, layout (if necessary), and printing will start with version patterns or patterns printed on the plastic sheet or rubber roller. The rubber roller will no longer sheet or pattern or pattern onto the surface of the beer.

Pros: Several colors can be applied in a single operation.

Disadvantages: lower productivity and not getting opacity strong prints. How to choose a suitable plastic sheet or rubber roller and oil, and so on.

1， The use of hot stamping foil and the color pattern engraved or font of the hot mold. Under controlled temperature and pressure. The surface of the emboss pattern of manufacturing color package or method of beer font member. Which is mounted on the operation only by fixing the press hot mold foil color on regional products across the pressure needed to be applied.

2, The paint surface treatment of plastic products (color) of the most commonly used techniques,

Can be divided into:

A general coloring, that this spray paints mostly by hand, do not have strong abrasion, easy to paint chips.

B, PU grade varnish this method is finished after the spray drying primer, then spray on the surface layer of the PU varnish method to achieve abrasion and gloss. General home appliances or many everyday items are through PU surface treatment.

C, UV grade varnish finish this method after spray primer and then sprayed with a layer of surface UV varnish, gloss, feel, rubbing can achieve very good results. General phone mold products and communications products die with such an approach.

 The use of the electrolytic plating method is electroplating the metal or alloy deposited on the surface, to form a uniform, dense and good adhesion of metal layers, called plating. Simple to understand, the physical and chemical changes, or in combination.

Such as many types of deposited metal can be obtained in various colors, with Compare similar process being relatively cheaper than in terms of prices.

What is Custom Plastic Injection Molding

 Most Chinese injection mold manufacturers complete international trade by providing customized services, but lack of real understanding of the real meaning of customers’ need for customized services, resulting in some mold manufacturers can not accurately complete the highly specialized manufacturing after signing contracts.

Just because a mold maker can facilitate the development of the original mold does not constitute real customer service (or ensure an ideal result). These mold manufacturers lack the ability to export complex injection molded parts for experienced reasons to complete with standardized specifications and tight tolerances.

How to evaluate injection molds consistent with your project needs is a critical criterion for project success. For example, components used in medical or aviation, automotive applications need to be truly sophisticated in design, engineering, and equipment use, compared to common civilian products.

Experience has the rich injection mold division’s concentration and the actual field ability. plastic molded parts used in such applications must comply with strict inspection specifications and compliance assembly instructions.
