3. FAQs about Custom Plastics Manufacturer Selection
When choosing a custom plastics manufacturer, there are less things to be considered so that you can choose the best one according to your specific requirement. Here below, some of the most frequently asked questions are provided for your help in choosing the best one according to your organization.
Q1: What should be considered while choosing a custom plastics manufacturer?
In selecting a custom plastics fabricator, take note of their technical skill, manufacturing capability, and industry experience in your marketplace. Note their experience with the molding process, e.g., injection molding, blow molding, or thermoforming, as applicable to your product type. To what level they can address your special needs, such as lead times, design support, and quality control, is equally relevant.
Q2: How critical is the ability of a manufacturer to rapid prototype?
Rapid prototyping is very helpful to try a product and validate the design before mass production. A supplier capable of delivering prototypes facilitates live iteration and reduces new product introduction risk. Precision and close-tolerance tolerances must be available, i.e., medical or automotive industry.
Q3: What are the indications of quality plastics manufacturing companies?
To know a company’s quality, ask them if they are certified, i.e., ISO 9001 or industry standards they follow. Get a sample of their finished work to examine their finish, tolerance, and product durability. Their past clients by reference, can also examine their reliability and customer service.
Q4: How long isthe typical lead time to make custom plastics?
Lead times will vary depending on manufacturing process, material, and project complexity. But the manufacturers that can speed up prototyping and streamline manufacturing processes can shorten lead times so your products hit the market sooner.
Q5: Must I take into account where a manufacturer is located when I am making a decision?
Location will determine lead times, shipping price, and communication speed. The offshored suppliers might be less expensive but the in-house manufacturers are more adaptable, communications are quicker, and transport time is quicker. When deciding, use the budget and schedule in mind.
Identifying the best-fit manufacturer of custom plastics is a time-consuming and effort-intensive process of developing their capability, competency, and reliability. Listening to their experience, quality control process, lead time, and ability to meet your unique requirement is of absolutely topmost importance. Resolution of these prime issues is critical to an efficient and productive partnership.
