1. Delivery Time

The sample will be produced within 5 days after the payment is confirmed; however, we can deliver the sample to you within 2 days if there is some products in stock.

2. Shipment

Normally, we choose the DHL, UPS, FedEx express for sample shipment, so the delivery time can be ensured. It's better if you have collection account of DHL, UPS, FedEx express, then you can only send the cost of the sample itself to us.

Order Information

If you have found what you are looking for, you can order by email or by fax. At the moment we only accept these two ways as the official order forms.

1. Order standard parts

Here standard parts mean the products we show on our printed or electronic catalogs with our own part numbers. When you order, to list our product model numbers are preferred. If you don't know our model numbers, please give us short descriptions of product you want to purchase. The useful information includes product shape, size, capacity, color, etc.After our sales team accepts your order request, usually they will work out the Proforma Invoice for your confirmation. The Proforma Invoice (P/I) has all the necessary dealing and delivery and our banking information. If customers confirm the P/I, he confirms the order in the meantime. We will immediately arrange the production.

2. Custom design and production

To meet various applications, customers often have modification requirements on our standard production, or ask us to work out new products with their schematic, drawing, graphics or real samples. After we receive these materials we usually have the time of 3 to 7 working days to evaluate the possibility of production. We will let customers know the evaluation result. If it is valid we will work out the quote and P/I as per customers' requirements.For custom products we will charge customers R&D cost and possibly new tooling cost.


We usually  accept 2 payment ways at this moment, and the payment is transferred and received before shipment.

1. T/T (telegraphic transfer or wire transfer).

Our bank takes about 1 to 5 days to receive payment from the different regions worldwide. The selected currency is US dollar and Euro. We have 2 accounts for separately receiving USD and Euro. When our sales representative quotes with USD, please transfer only USD to our specified USD account, to avoid the rejection of money by the bank.Customers please fill in the money transfer application forms exactly with the banking information we provide, especially the account number and beneficiary name. Even with the minor spelling name of the beneficiary or account number, the money will be rejected by the bank. If the money is rejected by our bank, customers need to ask your transferring bank to send cable correction message to our bank within 15 days, otherwise the money will be returned after 15 days.

2. Western Union transfer.

This is the fastest way to transfer money. We can receive money in several minutes if customers wire the money successfully. It is also an easy transfer & receiving way of money. After customers wire the money, please let us know the control numbers, sender's full name and the exact amount you send.
