  • ISO 14001 (Environmental)
  • Facility UL approval for Wire Harness (E95020) and for Cables (E12691)

System Assembly and Test

Our final assembly and test operation makes use of our in-house engineering capability to drive down cost whilst improving quality. For example, as a producer of the plastic parts that are used in complex system assembly solutions, we understand the trade-off between tolerances and product yield. Our design and engineering teams use this type of knowledge to provide detailed Design For Manufacturing (DFM), Design For Test (DFT) and other DFx input during the New Product Introduction (NPI) stage. In addition, our component engineers will utilise their intimate knowledge of our global supply chain in order to identify alternative supply sources – they will then suggest to our customers in order to drive cost reduction, yield improvement and/or risk reduction benefits.

Our electromechanical assembly capabilities include the following services:

  • Configure To Order (CTO)
  • Component Traceability
  • Low to Medium Volume batch manufacture
  • Higher Volume flowline and dedicated assembly cell solutions
  • Functional Test – with the ability to develop and manufacture test jigs in-house
  • HiPot Testing
  • Automated and Semi-Automated Conformal Coating Resin Encapsulation (Potting)

Cable and Harness

The manufacture of products to demanding standards for customers in the automotive, industrial & commercial, security, life safety, clean energy, medical and communications sectors is Season’s strength – and a key service we offer to these clients is cable and harness manufacture. Therefore, Season has obtained UL site approval for cable production (E12691) and wire harness assembly (E95020). We assemble a full range of cables used including co-axial, shielded, semi-rigid and flat cables.

The products produced require the use of in-house capabilities including:

  • Double overmoulding
  • Low pressure moulding
  • Insert moulding
  • Waterproof crimping
  • Ultrasonic and resistive welding
  • Large Gauge Crimping up to AWS #1

Plastic Injection Moulding / Thermoforming / Tool and Mould Manufacture

Season has a long history of producing plastics using its in-house capabilities. We see this as a key element in improving quality and reducing Time To Market (TTM) for our customers. Having all the key engineering skills for plastics, cable and harness, PCBA and systems assembly “under one roof” allows Season to assist customers in all aspects of product commercialisation. In particular, having the ability to design the plastic moulds with the customer, manufacture them in our Tool Room and produce first-off samples in-house really helps us to ensure that final assembly runs smoothly. The added ability to offer both injection moulding and thermoforming (vacuum forming) solutions, also ensures we can give our customers more options to reduce overall lifetime costs and TTM.

Our capabilities include: 

  • Plastic Injection Moulding
    • Class 10k and Class 100k clean room production options
    • Press sizes from 40 tonnes to 1300 tonnes
    • Vertical presses for Insert Moulding
    • Structural Foam moulding
    • Gas Assist moulding
    • In-house secondary processes including Heat Welding, Spraying, Silkscreen, Hot Stamping and Pad Printing 
  • Plastic Thermoforming (with Vacuum Forming)
    • Thick Gauge thermoforming
      • Part size up to 1.5m x 2.5m x 0.8m
      • Sheet thickness up to 10mm
      • 6 Axis automated machining
      • Epoxy, wood or aluminium tooling options
    • Thin Gauge thermoforming
      • Sheet thickness from 0.15mm to 2.0mm   
  • Tool and Mould Making

Global Service Provision

Our customers are looking for the best total cost solution for their products. This may mean using one of our six sites in the Far East, our three sites in North America and/or our two sites in Europe. Customers can “mix and match” services across sites – perhaps taking advantage of lower cost manufacture in Malaysia or China for their higher volume products and then using the UK site to provide local assembly services for lower volume, physically large products and/or for Warehousing, After Market or Logistics services.
