FAQs

Your Comprehensive MetalManufacturing Solution Provider

Please email us with the specification of the project, attach the part design drawing. If you would like to purchase plastic injection molds, the information needs to be told are: mold steel, plastic material and surface requirements of the part, the mold life, and the runner system you would like to use. If you want to purchase the molded plastic parts, please tell us the specific plastic material, the production quantity, the part surface treatment and the color for the plastic parts.

For some relatively simple products with simple structures, it’s good to quote by only the product photos. Send us the pictures of all dimensions and tell us the weight, that would be good. If the part is structurally complicated, and you don’t have the CAD design drawing, you could send the part to us by express, so that we give you the quote with the sample in hand.

These are how we guarantee: 1) Our customers could sign the NDA (Non Disclosure Agreement) with SAMMOLD to ensure that we will not plagiarize the design. 2) We are an OEM injection mold manufacturer, we do not have any channels and genes to sell such products, that’s one of the reason we don’t plagiarize or copy the part design. 3) For most projects, injection molded items are only parts of the product, which effectively prevents the whole product from being duplicated by manufacturing in one supplier.

No, we can’t. If you have any concept of sketch, we would suggest you to search the local design company to help you complete the whole design. If you have the design drawings but are not sure if it is suitable for injection molding process, we can help you with the part design modification and feasible optimization.

Yes, you can send us your sample, and we can provide reverse engineering services: we have scanners that can scan products to obtain 3D drawings and design and manufacture them.

Annual Output: Around 500Sets based our two facilities (depends on the size and complexity)

Generally speaking, in the injection mold industry, there are tooling life’s grade: 100,000 shots, 300,000 shots, 500,000 shots and 1 million shots. The tooling life is related to the mold steel, and the mold steel selection is based on the plastic material, parts surface treatment and the potential production quantity. Like other products in other industry, injection molds have a theoretical life time and the actual service life time. The theoretical life time would be listed on the quotation sheet from the beginning. How do we guarantee the mold life? When the mold is placed in SAMMOLD for production injection molding, we are responsible for the maintenance to ensure that the service life is close to the theoretical life. If the mold is exported to the customer’s country or region, under the proper using, the service life of the mold can be close to the theoretical life, but this is just like a car’s theoretical life and the actual service life is often difficult to achieve the exact same number. In the event of mold failure over a reasonable life time, our engineers will evaluate solutions for replacement of parts or mold repair by sending back to SAMMOLD’s workshop or having the local tooling manufacturer for assistance.

Yes, we provide the after-sales service. After the mold is exported, our sales engineers will continue to follow up the molding condition. During this stage, if any mold problem, our engineer will involves in the evaluation process and help to solve the issues.
