Injection molding (British English: moulding) is a manufacturing for producing parts from both thermoplastic and thermosetting plastic materials.  Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.

After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.

Step 1: Customer Order

When Poly Vision takes an order from a customer, a record will be created and information is gathered. The order will be submitted for processing after the customer provides the billing address, shipping address, and payment information. If there are any backorders, predefined discounts or any other conditions, they are applied to the order.

Step 2: Working Schedule

Material evaluation/Risk assessment is designed to help assess and improve client's product design, workmanship, functionality, reliability and safety, ensure the injected moulds are meeting your specifications and relevant international standards or legal regulations of intended market. In the end, a work schedule is established after the order is confirmed and each department's work is assigned.


Step 3: Material Purchasing

As soon as the work schedule is arranged, material purchasing is conducted by our procurement staff. Procurement staff performs all activities related to supply chain management. This includes, acting in a consultative role between Poly Vision and suppliers to inspect the companies, selecting optimal suppliers and maintain records of goods ordered and received. In addition, procurement department is also responsible for researching and evaluating suppliers, maintaining supplier database with evaluation points based on price, quality, selection, service, support & the supplier's reputation and history.

Injection Process Flowchart

Step 4: Granular Plastic Processing

With Injection Molding, granular plastic is fed by gravity from a hopper into a heated barrel. As the granules are slowly moved forward by a screw-type plunger, the plastic is forced into a heated chamber, where it is melted. Injection speeds are usually determined by performing viscosity curves. Process windows are performed varying the melt temperatures and holding pressures.

Step 5: Injection Mould Set Up

Injection mould set up is to install mould tool on mould machine.

Step 6: Data Setting

Mould injection machine's data is set for the first production on this stage. The machine is in excellent working condition and is capable of processing commodity as well as various plastic products.

Step 7: First Production Checking

Once the first production is made and the quality is assured, we will start  manufacturing them on a large scale.

Step 8: Mass Production

In the current mould-making industries, the challenge is to shorten the mould lead-time while maintaining the desired quality. This is one of the main demands from customers so as to maintain a competitive edge over the competition.  During the mass production, mould products are made with high-standard.

Step 9: Quality Control

The final exam of the products to ensure the quality of each production. Poly Vision's recent purchase of CMM is to make sure they got the job done properly.

Step 10: Packing

The packing staff check submitted packing sample according customer's packing specification and perform relevant transportation tests to make sure their products are well protected and shipped safely. Poly Vision assures your injection moulds are made correctly to your specifications and are well packed before delivery.

Step 11: Warehousing

Poly Vision's massive warehouse is one of their advantages which gives clients more options for their material storage and delivery needs.

Step 12: Delivery

Poly Vision's delivery team performs effectively. After plastic productions are delivered, we continue to provide our services until the first vehicle rolls off the line.
