The steel material of the Crate Mould(FURNITUREMOULD) is generally 718 or 2738, and it has to undergo multiple processing steps such as forging, CNC milling, roughing, quenching and tempering, and CNC milling. The plastics in the crate are generally plastics such as HDPE and PP.

The crate mould is generally a four-point hot runner, and the pusher plate is ejected. The advantages of using hot runners are: 1. Material saving, no need to cut gates, and then crush. 2. Speed up the cycle and increase production efficiency. 3. Reduce costs in the long run.

The crate mould has the following special requirements: 1. The exhaust effect is better, otherwise the plastic products will have black spots, etc., and the burnt will be severe. 2. The superimposed effect is better, the superimposed does not shake. 3. The line is better, no grind. 4. The mould should be highly polished, because the crates are daily necessities, so there should be no flash, burrs, etc., to avoid scratching the skin.

How to make a Crate Mould(FURNITUREMOULD)? First, the steel material should be selected for the mould base and the mould core cavity portion. For example, to produce a pair of four-out crate mould, pre-hardened steel with a hardness higher than 33 must be used as the mould base, and then the appropriate mould standard parts should be selected. Second, the hardness of each piece of steel must be controlled, not too hard.

Then, the friction and guiding parts of the crate mould must be finished and no manual work can be used. If you need to mould a durable tote, you must use a low melt index HDPE material, such as a plastic with an index of 4 or 6. Second, make sure the cooling system is optimal. To create a durable and durable hydraulic drive with the machine for automatic ejection, the ejection action during mould opening can be smoother.

Most of the world's crate mould manufacturers use accelerators to increase the injection speed of the melt. The design of the crate mould is equally important. The ejection mode of the crate mould is preferably designed to be mechanically ejected, so that the ejection operation can be completed when the mould is opened.

Due to the high precision of the manufacturing and processing precision of the Daily Necessities Mould(FURNITUREMOULD), the production and processing techniques are also complicated, so the processing and production costs of the general daily necessities mould are high. Molud manufacturers hope that the service life of the mould is longer, and the requirements for the use, maintenance and maintenance of the mould are higher, so as to maintain the working precision and prolong the service life. The choice of daily necessities mould materials is also an important condition for extending the service life of the mould. The daily necessities mould manufacturing materials must meet the following requirements:

1. The daily necessities mould steel must have good processing properties. When working in high temperature environment and heat treatment, the deformation should be small.

2. The flow path of the melt channel in the cavity of the daily necessities mould should be small, so the surface roughness of the working surface should be reduced. The steel should have good polishing performance. Impurities, no pores.

3. Excellent wear resistance. In order to maintain the dimensional accuracy of the mould structure of daily necessities mould for a long time, it is necessary to wear the working surface of the mould after moulding. In particular, when the raw material of the processed product contains a glass fiber-based hard filler, it is easy to accelerate the wear of the working face of the mould. For such a mould, it must have sufficient hardness and wear resistance.

4. Steel corrosion performance is good. In the plastic melt moulding production process, the plastic raw materials and some auxiliary materials should be in contact with the steel, which has a certain chemical corrosion effect on the steel. In order to maintain the corrosion resistance of daily necessities mould, it is necessary to choose corrosion-resistant alloy steel or high-quality carbon steel. If necessary, the surface should also be chrome-plated or nickel-plated.

5. Steel should have sufficient working strength. In addition to a certain degree of hardness after surface heat treatment, the selected steel should have sufficient core strength, because the injection mould is subjected to a large injection pressure and clamping force, so the core of the steel for daily necessities mould must be considered. Strength.

It goes without saying that the finished plastic parts are only as good as the daily necessities. A moulder can have the latest equipment, the best resin and the most experienced operators, but if the Daily Necessities Mould(FURNITUREMOULD) are not made correctly, there will definitely be problems. Choosing the right daily necessities mould makers often depends on the specifics of the moulder's needs. Each moulder has a different set of expectations and requirements. However, there are several things in common when choosing a daily necessities mould manufacturing partner.

1. Does the daily necessities mould manufacturer have a reputation for representing its products?

If moulders are looking for new daily necessities mould makers, don't forget to check the references. To ensure that daily necessities mould makers have a history of supplying quality everyday necessities, this is the first time a mould manufacturer can respond to demanding turnaround times. It is also important to check financial robustness through D&B or similar sources. If a moulder establishes a new relationship with a daily necessities mould maker and then finds it economically troublesome, it may waste a lot of time when the moulder starts looking for a new daily necessities mould making partner from scratch. .

2. Does the daily necessities mould manufacturer provide tool design in a usable format?

There are many types of CAD systems on the market today. It is essential to check whether the tool design in the CAD (along with the daily necessities mould) has a format that the moulder can refer to and use. This is especially important if any minor adjustments or repairs to the mould will be done by internal maintenance personnel.

3. Is the daily necessities mould manufacturer's workshop equipped with a newer machine?

It is important that the machines used to make the moulds for everyday necessities are not outdated to ensure the first time correctly manufactured high quality everyday necessities. Has the mould manufacturer updated the CNC equipment and tools? The basic recommendation is that the mould manufacturer has a 5-axis finishing machine with a high-speed spindle (over 12,000 rpm). Check that the daily necessities mould manufacturer's equipment is suitable for the type of mould required for the processor. Make sure to look at a finished daily necessities mould, pay attention to the mixture on the surface, and feel that the number of steps exceeds .001". Also, see if the shop has done a lot of manual finishing, such as grinding and benching. How much inventory is left, if it is greater than zero, ask how it controls the finished product to ensure accuracy.

4. Are daily necessities mould makers self-sufficient or outsourced?

Carefully inspect all the processes provided by the daily necessities mould manufacturer to see if you are outsourcing any key processes such as gun drills, EDM, etc. If the moulder finds that certain manufacturing and/or processing is outsourced, then there should be a degree of comfort in how this occurs, and understanding it from a time and quality perspective does not affect the finished mould.

In our daily work and study, we often see two concepts: plastic injection Furniture Mould(FURNITUREMOULD) and plastic furniture mould. What is the difference between the two? In fact, the injection mould and the plastic mould are moulds, which have the same place and are different. To find out the difference between them, we must first understand what is an injection moulding furniture mould and what is a plastic furniture mould.

The plastic furniture mould is a combined plastic mould for compression moulding, extrusion moulding, injection moulding, blow moulding and low foaming moulding, which is mainly composed of a female die base, a female die assembly and a female die combined clamping plate. The improved cavity is a punch with a variable core and consists of a punch combination substrate, a punch assembly, a punch combination clamping plate, a cavity cutting assembly and a side cutting combination plate. Coordinated changes of convex, concave and auxiliary moulding systems of dies. Can process a series of plastic parts with different shapes and sizes.

Injection mould for furniture is a tool for producing plastic products. It is also a tool that provides the complete structure and precise size of plastic products. Injection moulding is a processing method for the mass production of some complex shapes. Specifically, plastic melted by heat is injected into a mould cavity by an injection moulding machine under high pressure, and after cooling and curing, a moulded product is obtained. The injection mould consists of two parts: a moving mould and a fixed mould. The movable mould is installed on the movable mould of the injection moulding machine, and the fixed mould is installed on the fixed mould of the injection moulding machine. During injection moulding, the movable mould and the fixed mould are closed to form a casting system and a mould cavity. When the mould is opened, the movable mould and the fixed mould are separated to take out the plastic product. In order to reduce the heavy workload of mould design and manufacturing, most injection moulds use standard mould bases.
