What are the potential safety hazards in the injection molding workshop?

The safety of the tools used by workers in machining.

Workers' own safety in the process of loading and unloading molds and adjusting machines;

Workers use chemical items safely, many of which are flammable and toxic.

The smell of the raw materials, the toner used in the raw materials, and the additional powders are also toxic.

Safe use of water, electricity and gas. The safety of the mold, the safety of the machine, and the safe use of auxiliary equipment.

The safety door of the molding machine, the descending point of the manipulator, the link of the waterway and water pipe of the mold temperature machine, the use of the crane for lifting the mold, and the use of auxiliary materials (such as cleaning agents, rust inhibitors, release agents, etc. should not be placed in a high temperature place to prevent the use of cleaning screws) When cleaning the screw or injection material, the molding machine should pay attention to the splashing of the material, and the screw must be cleaned after the production of POM materials is shut down to prevent the decomposition of the material from causing air pressure in the screw ** Workshop fire safety, because injection molding requires high temperature, which can cause fire at any time. The most important thing is the electrical safety of the workshop, and all machines need to be grounded. Are the wires and cables peeling and old?

Prevent short circuits in circuits**.

1. Number of production per minute.

10. In the case of hundreds of stamping parts, in a short period of time to complete the process of feeding, stamping, discharging, waste discharge, etc., often occur personal, equipment and quality accidents.

2. Noise and vibration. There are also some problems and disadvantages in stamping processing. These problems are not entirely due to the stamping process and the die itself, but mainly due to the traditional stamping equipment and backward manual operation.

1. The purpose is to ensure the safety of injection molding operations and the safety of other people.

2. There are potential safety hazards in the injection molding workshop.

Crush injuries caused by mechanical transmission parts.

Injuries caused by electrical circuits.

Burns caused by the melt barrel area.

Smashing caused by the upper and lower molds.

3. Precautions for safe operation of injection molding machine:

The operator of the injection molding machine must be familiar with and understand the function of each switch button on the machine operation panel, and operate in strict accordance with the operating procedures and precautions.

Pre-boot operation requirements.

Before the machine is heated to start production, the cooling water valve should be opened to observe whether the water channel is unblocked.

Close the main power switch of the control box of the machine, then press the power button to start the power, and then press the heat button until the heating temperature reaches the set temperature (about 15 to 20 minutes), and then press the motor start button on the panel to start the oil pump motor.

Check whether the mold is firmly installed on the moving template and the fixed platen.

For machines that have been used for the first time and have not been used for a long time, after the oil pump is started, it is necessary to run no-load for a few minutes before starting to operate.

When the production is completed or the material is replaced, the barrel should be cleaned, set according to the processing temperature of the material to be replaced, the temperature is cleaned after the temperature is reached, the barrel is cleaned with clean secondary materials, and the injected material block is classified and placed in the designated position after cleaning.

When cleaning the material, the injection seat should be withdrawn.

When the two raw materials are alternated, the temperature setting should be adjusted according to the requirements of the raw materials.

Avoid leaving heat-sensitive and chemically reactive plastics in the barrel for too long, follow the physical properties table provided by the raw materials and raw material suppliers to clean the barrel, and when stopping and changing the mold to clean the barrel, the nozzle should be adjusted to an appropriate or higher temperature to keep the nozzle unobstructed, and then use a lower injection speed and pressure cleaning of the remaining rubber in the barrel.

When replacing plastics, it is necessary to ensure that there will be no chemical reaction when the old and new plastics are mixed, and other plastics can be used to remove all the old materials in the melt cartridge.

Summary. Hello dear! Hidden dangers of production safety in mold workshop:

The first is the safety of electricity, all kinds of electrical equipment need to be checked regularly to prevent short circuit due to line aging; The second is the fire hazard, the mold processing workshop usually uses oil and some chemical reagents, which requires strict control of the fire source and regular inspection of fire protection facilities; Finally, machining safety should also be noted, employees must be trained to work, to prevent mechanical injury, for more dangerous processing equipment such as grinders, wire cutting and other equipment need to be demarcated a separate isolation area to be responsible.

Hello dear, there are some safety risks in the production process of the injection molding workshop, and the following are some common risks and possible harmful consequences:1Deep damage when operating a machine:

Workers may suffer serious deep injuries while operating an injection molding machine, such as a finger getting stuck in the machine. This can lead to long-term disability and job interruptions. 2.

Burns and Chemical Hazards: While preheating injection molding materials, cleaning molds, and maintaining injection molding machines and equipment, workers may be exposed to hot and chemical materials, such as mold cleaners and plastic additives, near the holes. Long-term chronic ongoing exposure can cause health damage such as common and age-related health problems, including**itching, headaches, eye pain, and long-term lung problems.

3.Failure of mechanical or electrical equipment and fire: When equipment is damaged or malfunctions, it may result in fire or other accidental pressure release resulting in injury to workers.

It may be necessary to use safety measures and procedures to avoid such problems, and to regularly service, maintain, repair and update the equipment. 4.Accidents caused by improper human work:

Operator misconduct due to work stress, negligence, human error, or other reasons can lead to unexpected events such as mechanical failure, chemical leaks, limited visibility, falls from heights, and other unexpected events, and lead to threats to workers' health and life safety. In order to reduce the consequences of these risks and hazards, injection molding shops generally implement strict safety measures and process specifications. For example, equipment maintenance, early warning of parts and consumables, employee safety education, appropriate work clothes, regular equipment inspection and maintenance, etc.

At the same time, shop floor safety and risk management must be clear to all workers and comply with relevant protocols and regulations.

Hello, the potential safety hazards in the production of the mold workshop are: 1. The safety awareness of some employees in the workshop is weak, and the safety awareness of employees is further strengthened through training and class meetings. 2. The equipment point inspection work is not detailed enough, and it is necessary to further strengthen the point inspection of the equipment to ensure the safe operation of the workshop equipment.

3. The fire extinguisher is not complete enough, and the existing 3 bottles of fire extinguishers in the workshop need to be supplemented, and they need to be applied and registered with the company in the equipment and supplement. 4. The broken glass on the site is sometimes not cleaned in time, and it is further strengthened to meet the specifications of the actual site.
