Rubber transfer moulding machine

Types of the rubber transfer moulding machine

Rubber transfer moulding machines are used to produce rubber parts by transferring pre-heated raw material into moulds for curing and shaping.

• Conventional Transfer Machines:

  These are the older generation of TCR machines, which are well known for not featuring any automatic control. The unloading and loading of the material is a complete manual process, and the hydraulic press used is usually stationary.

• Automated Transfer Machines:

  In contrast to the manual operation of the conventional ones, these involve automatic or semi-automatic control, which makes it easier to load and unload materials. The hydraulic press used may be stationary or sliding. In some cases, these machines may have multiple moulding stations which allow for lower cycle times.

• Pneumatic Transfer Machines:

  As the name gate, this machine uses air pressure to operate, for which it may require a different compressor or more moulding stations to be efficient. This is a good option when electric energy sources are not available, but it usually has a slower cycle time.

• Injection-Transfer Hybrid Machines:

  These machines combine the advantages of transfer and injection moulding processes offering higher precision and control in the moulding of rubber materials.

• Robot-Automated Transfer Systems:

  These advanced systems use robotic arms for material transfer increasing precision speed and flexibility in production.

Specifications and maintenance of rubber transfer moulding machines

Specifications

The following are specifications one must consider when looking for a transfer moulding machine for rubber.

• Suitable materials: As previously stated, transfer moulding machines work by softening rubber materials. However, different types of rubber require distinct temperature and pressure settings. Therefore, businesses need to choose machines compatible with their moulding materials.
• Production capacity: A moulding machine's production capacity indicates the highest number of moulded products it can produce within a specific timeframe. Machines with higher production capacities cost more. Therefore, businesses that require the machines to produce large volumes of moulded products should get those with higher production capacities. Typically, it's great to consider moulding speed, daily operating hours, and yield rate when calculating the production capacity.
• Press force: The press force or clamping force usually exerted by the machine when compressing the material in the mould is another important specification for moulding machines. It is measured in tons or kilonewtons (kN). For instance, a small machine might have a press force of around 15 to 30 ton, while larger industrial-scale machines could have press forces of several hundred tons.
• Mould dimensions: Mould dimensions are also key specifications for rubber transfer moulding machines. The dimensions will show the sizes and shapes of the rubber products that the machines can create. Machines that have bigger mould dimensions make larger rubber products.
• Energy consumption: This is the power or energy the moulding machine uses. Power is usually measured in kilowatts (kW). More energy-efficient machines help to reduce production costs.

Maintenance

Machines require maintenance practices to keep them in good shape. The following are some maintenance practices for a transfer rubber moulding machine:

• Regularcleaning: Cleaning the machine regularly is an important maintenance practice. It helps prevent the build-up of debris, product residue, and lubricant contamination. Cleaning the machine regularly enhances the operation of the machine, reducing the chances of break-downs and mould damages.
• Lubricate movingparts: Lubricating the machine's moving parts is a great way of caring for the equipment. It minimises wear and tear and ensures smooth operation. It's important to know the right lubricants for use in each product part and establish a regular lubrication schedule.
• Electrical and hydraulic system check: Regular checks of the hydraulic and electrical systems help to identify potential issues like leaks, loose connections, and frayed wires before they escalate into major problems requiring costly repairs.
• Periodic pro-fessional servicing: Buying a moulding machine is a huge investment for business owners. Therefore, it is only wise to establish a maintenance schedule and follow it. This will include regular professional servicing and inspection of the machine. Setting a maintenance schedule and sticking to it helps to prolong the life of the moulding machine.

Rubber transfer moulding machine FAQ

Q1: Is the performance of transfer moulding better than compression moulding?

A1: Yes, transfer moulding has better performance than compression moulding. Some materials, like rubber, can flow better in transfer than in compression. The process can create smaller parts with better quality, like more precise dimensions and better surface finish.

Q2: Which materials are commonly used with transfer moulding?

A2: Several materials can be used in the transfer moulding process. Some thermosetting plastics can be used are epoxy, phenolic, unsaturated polyester, etc. Phenolic is the one used most often. The rubber transfer moulding material is also applicable to rubber.

Q3: What is the difference between transfer and injection moulding?

A3: The two processes are similar in that they both involve heating material until it is molten and then forcing it into a mould to cool and solidify. But transfer moulding is better for large parts, while injection moulding is more efficient for small parts. Also, the material heating method is different. In transfer moulding, the material gets heated in the chamber. But in injection moulding, the heating happens in the cylinder.

Q4: What are the advantages of using transfer moulding?

A4: The rubber transfer moulding machine makes parts with better surface finishes and more precise dimensions. It also wastes less material because scrap is easier to manage. The process operates at higher production speeds than compression moulding. The moulds cost less because they do not need to be made very thick.

Q5: What are the limitations of transfer moulding?

A5: The main drawback of the transfer moulding process is the cost. It is more expensive than compression moulding. Also, the rubber transfer moulding machine does not work well with large parts. Other methods like compression or vacuum transfer would be better for them.
