Application of 3+2 CNC Machining in Mold Making Factory

Plastic injection mold manufacturers have long embraced simultaneous multiple-axis machining on machine tools with five or more axes, but more and more China injection mold makers have begun machining mold components on multiaxis platforms in the past few years, said Charlie Chan, engineering manager HS Mold & Die Co.,LTD

He mentioned, however, that the common approach for machining mold parts in houses is 3+2, or 5-axis positional machining. According to his estimate, about 80% to875% of the multi-axis work is performed via 3+2 rather than simultaneous when cutting up to five sides of a prismatic metal workpiece in one fixturing.

What is 3+2 CNC Machining

3+2 (5 axis) CNC machining, also called “positional five-axis machining”, is a technique whereby a three-axis milling program is executed with the cutting tool locked in a tilted position using the 5-axis machine’s two rotational axes, hence the name, 3+2 machining. During the machining process, the fourth and fifth axes are used to rotate the cutting tool in a fixed position rather than to manipulate the tool continuously.  On a standard three-axis machine, the only part face that the CNC machine could cut with a cutting tool in its normal position is the horizontal face that faces directly at the spindle. 

3+2 CNC Machining Advantages

Compared to conventional three-axis machining, the main advantage of 3+2 CNC machining is the reduction of setup time. According to data from our mold making shop, we could save easily 20% to 25% in setup time because we don’t have to handle that part multiple times.”

Another big benefit of 3+2 CNC Machining is that it allows for the use of a shorter, more rigid cutting tool. With 3+2 machining, the spindle head can be lowered closer to the work piece with the tool angled toward the part surface.  This means that a good surface finish and more accurate dimensional results can be achieved .This helps to improve part accuracy by being able to position a work piece so that short, rigid cutting tools are applied, such as when producing undercuts in mold cavities and steep wall inserts in addition, with 3+2 machining, we can use standard, off-the-shelf tools

 Rather than using some custom, extra-long tool or holder and risk vibration, this helps to save money easily by 10% to 15% in injection mold costs because there is no need to use special tools for mold manufacturers in china, 3+2 Machining is an ideal option because they can use more off-the-shelf, standard catalog tooling. They have the freedom to reach into my part at different angles without using an especially long tool or special to make that feature on that part.

Application of 3+2 CNC Machining

Where applicable, 3+2 machining will save time and improve operations.This technique is more and more popular with mold making company because it offers great convenience while deep cavities or inserts in complex plastic molds that would otherwise have to be machined with long, slender tools or with tool extensions. Long, slender tools increase the risk of deflection or chatter and tool extensions can create clearance problems. Using 3+2 machining also allows undercuts in cavities and steep walls on standing mold cores to be machined directly. This technique might reduce or eliminate operations for electrical discharge machining (EDM).Relatively few parts are not suitable for 3+2 machining, including complex components. 3+2 CNC Machining is usually used to machine below parts:

deep cavities or inserts in complex plastic molds

certain types of parts from the solid rather than from a complex casting

Drilling holes of metal parts at compound angles such as  aluminum brake cylinders in a single setup

We are a China injection mold maker and our CNC machining center has both 3+2 and full 5 axis machining capability, capable of making prototypes and production parts as fast as one day.  Reach out HS Mold and see how we could benefit your next CNC rapid prototyping or low-volume manufacturing project.

Introduction to injection molding process of taillight masks

1. Introduction to taillight masks Let’s make a brief introduction to taillight masks. Taillight masks are available in single-color, double-color and three-color products. Three-color products are divided into true three-color and false three-color. True three-color is a three-shot three-station mold, and false three-color is a three-shot two-station mold. Three-color products are relatively…

The Working Principle of Plastic Injection Mold

Plastic injection mold is an important plastic processing tool, through which plastic raw materials are transformed into products of various shapes and specifications. The principle of injection mold can be summarized as the following steps:

1. Plasticizing and injection

First of all, plastic raw materials undergo a series of processing treatments, such as drying, screening, mixing, etc., to become plasticized materials suitable for injection molding. In the heating barrel of the injection machine, the plastic begins to melt and plasticize under the action of heat, forming a uniform molten state. Subsequently, the plasticized plastic is pushed into the nozzle of the injection machine through the pushing action of the plunger or screw. When the plastic in the nozzle accumulates to a certain amount, the driving force of the injection machine stops, and the nozzle of the injection machine injects plastic into the pouring system of the mold. At this point, the pouring system introduces the plastic into the mold cavity.

2. Mold filling

Under the pressure of the injection machine, the plastic flows in the mold cavity and fills the entire cavity. In this process, the plastic is subjected to pressure and temperature, and continues to plasticize and melt. At the same time, the cooling system of the mold begins to work, and the heat inside the mold is taken away by the cooling channel or the cooling medium, so that the plastic is quickly cooled and shaped in the cavity.

3. Mold opening and release

When the plastic is cooled and hardened in the mold cavity, the mold is opened and the molded plastic product is pushed out of the mold cavity or removed from the mold. This process is called opening and stripping. When the mold is opened, the parting surface of the mold is opened, and the product is pushed out or taken out of the mold. The mold is then closed and ready for the next round of injection molding.

4. Other auxiliary actions

In the process of injection molding, some other auxiliary actions are also involved, such as the exhaust of the mold, the adjustment of the ejector mechanism, and the control of the mold temperature. These actions are essential to ensure the quality of the product and the stability of the production.

In summary, the principle of plastic injection mold mainly involves plasticizing, injection, filling, cooling, mold opening and mold release steps. These steps are coordinated to complete the injection molding process of plastic products. With the continuous progress of science and technology, plastic injection molding technology is also developing, and new injection machines, molds and processes continue to emerge, providing more choices and possibilities for the production of plastic products.

Hey everyone, let's discuss the PFA injection molding!

[enjoy-comfort-life]

Causes of brittle injection molded products

Product brittleness is often due to material degradation during injection molding or other reasons.

Injection molding problems: <1> The barrel temperature is low, increase the barrel temperature; <2> The nozzle temperature is low, increase it; <3> If the material is easily thermally degraded, reduce the temperature of the barrel nozzle; <4> Increase the injection speed; <5> Increase the injection pressure; <6> Increase the injection time; <7> Increase the full pressure time; <8> mold temperature is too low, increase it; <9> The internal stress of the workpiece is large, and the internal stress is reduced; <10> There are stitching lines in the parts, try to reduce or eliminate them; <11>The screw speed is too high and the material is degraded.

Mold problem: ①The product design is too thin; ②The gate is too small; ③ The shunt channel is too small; ④Add reinforcement ribs and rounded inner corners to the finished product.

Material problem: ①Material contamination; ② The material is not dried well; ③ There are volatiles in the material; ④There are too many recycled materials in the material or too many recycled materials; ⑤ The material strength is low.

Equipment problems: ①The plasticizing capacity is too small; ② There are obstacles in the barrel to promote material degradation. Therefore, in the production process, we must avoid the above problems, and constantly monitor the production process of the mold to prevent the product from becoming brittle.
