How to protect injection molding machine-Dakumar injection machine

Injection molding machine is one of commonly used equipment in the plastic processing industry,it is usually long hours,so how to guarantee the stability of injection machine in continuous production of normal work,no matter for injection machine manufacturer or user is a worthy of attention and efforts to solve the problem.

the ideal working temperature of hydraulic system should between 45 ℃ to 50 ℃,should pay attention to daily check for leaks,replace worn seals,as early as possible to tighten loose coupling, etc.After repair to check the amount of oil,gas supply in time.To use the appropriate hydraulic oil, and periodically check the hydraulic oil oxidation degree (to judge from the color of deep),more than a certain number of work hours after explorers oil is absolutely necessary.Oil filter should be cleaned once every three months,check oil screen damage at the same time,the cooler should be cleaned once a year,or on the basis of their ability to work ever reduce,cleaning,cooling water should choose soft (no minerals) is preferred.

Electrical parts,need to regularly check the terminal position and tighten,motor each year for regular cleaning.Heating tube of burnt down in the normal production is less visible,to pay attention to the working condition of temperature controller for this purpose.The contactor used for electric parts,if found contact with overheating,noise or breaking of fire is very big,has said the damage,should be replaced as soon as possible.And should be timely check the outside disturbance to the computer control part.

Mechanical parts,template parallelism can reflect the status of the clamping part,most template parallelism adjustment shall be controlled by professional personnel according to the working steps,or adjust the improper damage to the machine.Regularly use mould thickness adjustment system,use the same mold production machine for a long time,the inspection must be conducted to avoid failure.For the central lubrication system, even daily bearing injection system check,maintain the smooth action.

How to make a high quality plastic injection mould-Sino mould

Quality of the mould,it will directly affect the product quality, yield, cost,production of new products and old products renewal cycle,product structure adjustment speed and market competitiveness,therefore,the economic situation puts forward higher and higher requirements about the quality of the mould.

There are four aspets control mould quality:

1.product quality:product size stability, compliance,roughness on the surface of the products, products material utilization ratio and so on;
2. the service life:on the premise of ensure the quality of the products,the mould can be done by a number of fabrication or production cycles.
3. the use mould maintenance: whether to belong to the most convenient to use,easy mold release, production of auxiliary time as short as possible;
4. the maintenance cost,periodic maintenance and so on.

Mould design is reasonable,the die structure design,compact structure,easy to operate.As far as possible to reduce the maintenance one parts need to tear open outfit.The selection of die materials,both to meet customer requirements for product quality,to surface strengthening of main forming parts,mold correct use and maintenance,is also a big factor to improve the quality of the mould.

Using standard mold componets

Standard mold part are president in most modern molds.A whole mold making industry has been created which manufactures and supplies standard mold components based on a catalogue selection and order syste,.Faster delivery and financially competitive are ones of the major attractions to the mold maker.It is also an important factor if the mold has break down and it is required for production.

The advantage of using standard mold components include:

1.       shorter mold construction lead time.

2.       Increased machining capacity in house.

3.       Ease of mold maintenance

4.       Reduce mold downtime

5.       Reduce the overall long-tem costs.

The main disadvantage concerned with the use of standard mold components tends to be associated with the following:

1.       Reliance upon one specific source of supply

2.       Failure to supply on time.It is a rare occurrence with most suppliers,but it should be considered the delivery time quoted by supplier and place order on time.

3.       Mistakes in part ordering caused longer mold downtime.

Standard parts system is divided into two general groups

1.       standard mold base system

2.       Accessory components,like ejection,slide,cooling and so on.
