Key things to consider when choosing an Injection Moulding supplier

Polymer Selection

Polymer selection is an important part of injection moulding so when looking at suppliers it is key to identify whether they can assist with polymer selection. There are different types of synthetic plastics that include:

  • Standard polymers
  • Engineering polymers
  • High-performance polymers

There are different benefits of each type of polymer so it is important for suppliers to be able to inform and advise on what is suitable per the job requirements.

Design Capabilities and In-house Tool Making

When selecting an injection moulding supplier, it is beneficial to choose one that has design capabilities and in-house tool making facilities. This means that the process of injection moulding including the design stage and tool making is done under one roof. This makes it easier for teams to communicate at each stage of the process and it eliminates possible delays and encourages less room for mistakes.

Certified Quality Management System

Quality Management Systems (QMS) were designed to help organisations meet the needs of customers and key stakeholders. A QMS is a formal system that documents the processes, procedures and responsibilities in order to successfully achieve the aims of a project, whether this is tool making or injection moulding. A recognised international QMS system is ISO 9001 and is based on 7 quality management principles, which include having a strong customer focus, the involvement of top management, and a drive for continual improvement.

Post Moulding Services

Services don’t stop once the parts are made. Ultrasonic welding is a technique commonly used in the plastic injection moulding industry to join two components together with high-frequency ultrasonic vibrations. The finished product consists of glue-less joints free from connective bolts, screws or fastenings.

One of the biggest benefits of ultrasonic welding is that it is a cost-effective way to join parts, and helps designers overcome design constraints sometimes experienced with other joining methods. Our ultrasonic welding facilities can weld a variety of thermoplastic components. The equipment provides a high degree of reliability and repeatability and can be used for other functions including riveting, swaging and inserting.

Pad printing can add detail to your product to increase usability, add a personal touch and is a useful way of emphasising certain parts of the product. For example, you can pad print safety features onto a device to illustrate the correct operation to users.

At WSM Plastics, we have two colour pad printing in-house and have an established supply chain for Painting, RFI Coating and other special finishing operations. The flexibility of pad printing allows us to print high-resolution, defined designs onto almost any product regardless of size or shape, while the variety of inks available means that we can match the colours to suit your company’s corporate colours and branding guidelines.

The benefits of Project Management

Project management is put in place with the aim of increasing customer satisfaction. A project manager helps deliver the desired results of a project, whilst avoiding any unexpected costs and meeting the set deadlines. A project manager will also outline the risks of the project and work to mitigate them. Effective project management delivers project updates and information to the internal personnel and acts as a go-between with the client and the company. This decreases confusions and increases successful project completion.

Ranging machine sizes for flexibility

Injection moulding machines are referred to in their clamp tonnage, the tonnage will determine the size and number of cavities that can be produced. The bigger the tonnage means a larger component with a higher number of cavities that can be produced. For example a small machine has a 22 tonne clamp tonnage and a large machine has a 650 tonne clamp.

Post Moulding Services offed by WSM Plastics

At WSM Plastics, our services don’t stop once the parts are made. We are able to offer secondary operation services to complement our tool making and injection moulding.

Pad Printing

As part of our post-moulding services, we offer pad printing so you can include your name, instruction information or company logo.

Adding detail to your product can increase usability, add a personal touch and is a useful way of emphasising certain parts of the product. For example, you can pad print safety features onto a device to illustrate the correct operation to users.

We have two colour pad printing in-house and have an established supply chain for Painting, RFI Coating and other special finishing operations.

Soldering

 We offer customers a full-integrated service where we work with you to develop your idea into a finished product. We can also design and manufacture any special purpose assembly and test equipment required in-house. Soldering is a process in which two or more metal items are joined together by melting and then flowing a filler metal into the joint-the filler metal having a relatively low melting point.

One of our current offerings includes soldering for Printed Circuit Boards and cable assemblies. Whether you require rework or small to medium batch build, our trained team carries out soldering to IPC-A-610 standards.

The Importance of Total Productive Maintenance

What is Total Productive Maintenance (TPM)?

Total Productive Maintenance (TPM) is a system of maintaining and improving production, safety and quality systems of machinery in order to produce high-quality end results, valued by an organisation and its customers. The main objective of TPM is to increase the effectiveness of equipment

Result of this approach will:

  • Reduce breakdowns
  • Ensure there is no small stops or slow running
  • Reduce the total number of defects

Defects, breakdowns and disruptions to the running of equipment can mean big losses to a business so the use of TPM improves the effectiveness of production lines. In addition to these values, it supports the practice of a safe working environment.

Implementation

To introduce a TPM system to any manufacturing environment, there are a series of steps to follow:

  1. Initial evaluation of TPM level
  2. Introductory Education and Propaganda (IEP) for TPM
  3. Formation of TPM committee
  4. Development of a master plan for TPM implementation
  5. Stage by stage training to the employees and stakeholders on all eight pillars of TPM
  6. Implementation preparation process
  7. Establishing the TPM policies and goals and development of a road map for TPM implementation

The foundation of TPM is “5S” and is itself an integral part of a lean manufacturing approach and continuous improvement.

Traditionally TPM has “8 Pillars” that focus on proactive and preventative techniques to improve the reliability of equipment. These pillars include autonomous and planned maintenance, placing more ownership of equipment maintenance in the hands of the operator and having a proactive approach to maintenance to achieve the desired approach.

The results of a successful TPM approach will ultimately be seen in Overall Equipment Effectiveness (OEE), which is tightly coupled with the TPM goals above.
