Chinese Battery Box Mold Maker

We are engaged in manufacturing, exporting and supplying a wide range of battery box molds.The offered range is available in various specifications as per customers’ requirements. Due to customers' trust, every year we export about 80sets battery box molds to all over the world and has enjoyed wide acclaim.

Commonly, battery box includes two parts: one is battery box base, another one is battery box cover. Below are specifications of battery box molds made by Sino Mould:

Product material: PP

Mold steel: DIN1.2738, 718H, P20

Mold life: 500K

Runner type: hot runner, one tip for battery box cover mold; but for battery box base mold, we suggest one tip for one lattice

Eject way: ejector pin for battery box cover; stripper plate for battery box base

The most important key point for battery box mold is to master how to control each lattice size, neither too loose nor too tight. If it is too loose, the battery box will get swell when charging; If it is too tight, the battery box will fail to charge. So our company had spent a lot of time to figure out the best solution to control the size. Before mold design, our engineer will do moldflow to analysis the deformation. According to the moldflow report, our designers will choose suitable position for injection point to keep injection balance. Also we will make the water channel more intensive to reach good cooling effect.

Energy-Saving Injection Molding Machine

DKM Machinery was established in 1990, had already become one of Chinese famous injection molding machine manufacturer. We has innovated many types of injection molding machines, such as standard injection molding machine, PET injection molding machine, PVC injection molding machine, servo injection molding machine, high speed injection machine and so on. Below information is about our best-selling machine, servo injection molding machine.
 
Many important features make it becomes best-selling machine:
1. High energy savings: under normal operating conditions, compared with conventional hydraulic injection molding machines, energy savings of 20-80% can be achieved. Energy saving machine can reduce production cost and improve control precision of speed and pressure control. The service life of machine can be also extended.

2.  Mould stability: compared with conventional injection molding machines, repeatability is greatly improved due to servo motor closed-loop control.

3. Quick operation: the machine runs at much lower noise levels, particularly in low speed applications.

4.  Better oil temperature stability: the servo system only delivers hydraulic oil as it is needed for the various functions. This prevents unnecessary generation of heat and substantially reduces oil cooling requirements.

5. Quick response: featuring a dynamic servo motor with a response time of only 0.05second.

6. Reliable holding pressure: compared with traditional hydraulic machine the holding pressure is more stable and does not have limitation.

7. High precision: the machine is applied with Mirle or Techmation control system and Yuken valve, which enable it to control each shot precisely on weight and position and reduce errors in molding tolerance to get high precision molding.
 
Energy-saving injection machine is suitable for industrial containers and pallets, chairs and tables, home appliances, automotive parts etc. We can offer customized machine according to your specification. So if you need injection molding machine to realize mass production, please kindly contact me, I will choose suitable machine for you and quote for you.

Plastic Chair Molding Service

Sino is specialized in design and manufacture various types of chair mold, like PC chair mold, PP chair mold, gas assisted chair mold, child chair mold and so on. Almost most of the mold company can make chair mold, but seldom of them know how to make a high quality chair mold with good price. That’s why more and more company closed down, while Sino become stronger and stronger.

 

Some key points to check if the chair molds high quality and not:

1. Chair mold running cycle time

If the chair weight from 1700g to 2400g, the cycle time should be 35s to 50s. If the machine plastic melt and inject are with accumulators. Please check how they make the cooling channel? The cooling channel is extra in and out?

 

2. Chair mold guaranteed life

Most of manufacturers will say that their molds will have one millions guaranteed life. But God now how can they guarantee. Can the mold run 1 million shorts without any flashes? Because if you accept to cut the flash by your workers heavy labor, I think you can use this mold for 10 millions shorts. So you need to check the steel hardness, and in the mold if there is any parting area were welded. Normally the steel hardness should be HRC33.

 

3. Double check the parting line finishing, if there has any sharp edges?

First you have to check the chair mold parting line is correct or not. You have to know how the CNC milling the cavity and core. Are they one stage finishing or several stage finishing?

 

4. Double check the wall thickness, is it even or not?

The uneven thick will cause the injection not balance and also will cause the cooling time not even, which will affect the injection speed slow down and also will cause the shrinkage marks. If the CNC milling is too rough, you can never get a chair with thickness even.

5. Check the stackable

When the chair plastic design is doing, we have to check its stackability. And you also need to consider the deform possibility of the chair molding.
 

All in all, one high quality chair mold must be with short cycle time, long mold life, perfect parting line finishing, good stackability, well air vent design, less weight but strong enough. If you have idea want to develop chair mold, please kindly contact me, I am glad to offer you best chair molding solution.

How to make a good paint bucket mould? Sino has accumualted rich experiecne in design and inspection system.

1. When get order from customer, Sino will ask for material specifiaction, stacking, dropping and assembling requirement, weight and size tolearance. We will make mold-flow to anaysis the product flling effect, and will send report to customer.

2. We pay high attention on wall thickness, since for paint bucket mould, it is easily cause the barrel of uneven thickness. If the cooling is not equal in the different area of the pail mould core and cavity, this will cause the following difference of the melted material, the more hot area flowance will be bigger and the colder area the flowance will be smaller. then the hot area's pail wall thickness will be thicker. The temperature difference normally caused at least 0.05mm... Normally, the pail mould the interlock height should be 20 to 30% of the plastic pail's height, for example the smaller pail should be 20%, the bigger pail mould should be around 30% height. The machining process is meaning which kind of machining should we select and what we should take care when we make the machining to the pail mould core and cavity.

3. Drop test process. Sino has standard drop test procedure and pre-analysis report before making painting bucket. Therefore, the drop test can be easily passed by our QC department.

While in the daily maintenance, we also need to check the whole parts of the plastic injection molds, like the safety pin, safety screw, side guard and so on.

1. Check and test cooling channel on airproof guard.

2. Measurement of heating system under H.R. Instruction.

3. Ensuring Hydraulic C. moving under proper Conditions and w/o Oil-leak Problem.

4. Adding enough Lubricant for smooth core pulling movements.

5. Make sure lubrication of the sliding mold parts.

6. Measure hydraulic system’s pressurization.

Mould storage: after all techniques finished, physical dryness &antirust treatments are required according. Finally, fixing & storing mould under dry conditions.
